You might also need one of our tested 128GB, 256GB or 512GB NVMe drives or a clear acrylic case to protect your RPi5 and NVMe Base.

NVMe Base is a PCIe extension board for Raspberry Pi 5. Simply populate it with an M-key NVMe SSD (2230 to 2280 sizes supported) and mount it under your Pi for a compact and fast storage solution - It even comes with rubber feet!

It's the perfect solution for turning your Raspberry Pi 5 into a file server, media centre, reverse proxy, etc. - really any task that benefits from large amounts of fast storage, especially with random high operations per second (IOPS) workloads. In short it's a game changer!

NVMe base follows the new "PIP" design guidelines provided by Raspberry Pi ensuring that it will be easy to use and be supported long term by updates to Raspberry Pi OS - though it is very early days and things are improving rapidly there!

What's in the box?

1 x NVMe Base PCB with M.2 Slot (M-Key)
1 x 'PCIe Pipe' Flat Flex Cable
4 x Rubber feet
1 x M2 bolt and 2x nuts for SSD mounting
4 x 7mm M2.5 standoffs for base mounting
8 x short M2.5 bolts for base mounting 
4 x long M2.5 bolts for 'pass-thru' mounting with a HAT

You might also need a NVMe drive. Make sure you choose one that fits your NVMe board.

Driver compatibility

We have tested NVMe Base with the following M.2 NVMe drives successfully. We have usually tested one drive from one batch, so this is not comprehensive, or an 'Approved' list, but it's a good guide for drives to seek out:

• AData Legend 700
• AData Legend 800
• AData XPG SX8200 Pro
• Axe Memory Generic Drive
• Crucial P2 M.2
• Crucial P3 M.2
• Crucial P3 Plus M.2
• Inland PCIe NVMe SSD
• Kingston KC3000
• Kioxia Exceria NVMe SSD
• Kioxia Exceria G2 NVMe SSD
• Lexar NM620
• Lexar NM710
• Netac NV2000 NVMe SSD
• Netac NV3000 NVMe SSD
• Origin Inception TLC830 Pro NVMe
• PNY CS1030
• Sabrent Rocket 4.0
• Sabrent Rocket Nano
• Samsung 980
• Samsung 980 Pro (500GB/1TB)
• Team MP33
• Western Digital Black SN750 SE (Phison Controller

' Maybe' List. Works with quirks/not ideal.

These drives either needed extra power, were a bit quirky when we tested them or we've had reports of them being problematic. It may just be the drive we had, but they're probably best avoided.

• Kioxia BG4 2230. Performance very patchy. Runs at quite a high temp.
• Patriot P300 - These drives have various controllers, some of which seem to be incompatible at this time.
• Patriot P310 - These drives have various controllers, some of which seem to be incompatible at this time.
• Samsung 970 EVO Plus. Runs at a higher temp. Some user reports of problems under heavy load or not showing up on boot.
• Samsung 980 Pro (250GB). Reports of this size not working.
• WD Blue SN550. Our fresh unit could be used as storage but could not be booted from.
• WD Red SN700. Slow to boot first time, but worked and booted OK.
• WD SN740. Our fresh unit worked well. YMMV.
• WD Black SN770. Our fresh unit worked fine. YMMV.
• Patriot P300. All units we've tested work but we have heard of a 256GB/1TB variant that doesn't.

'Avoid' List. We've had problems or reports of problems.

• Transcend 110Q (TS500GMTE110Q)
• WD Green/Blue/Red/Black not in the above list. Variable results or not working because of quirks of a SanDisk controller/firmware. Our SN350 and SN570 prevented the RPi 5 from booting at all especially.

Otherwise most M.2 NVMe drive (Not SATA!) you have lying around should work fine.

Firmware

For the most hassle-free experience, make sure your Raspberry Pi OS is up to date, and your RPi 5 firmware is updated to 2023-12-06 (Dec 6th) or newer. This supports all the features of the RPi PCIe spec and means you don't have to mess with config files to get started.

Software update on the RPi OS should do this for you, but to force it you can:

• open a Terminal (Ctrl-Alt-T)
• run sudo raspi-config and choose 'Latest' under Advanced Options > Bootloader Version.

Running sudo rpi-eeprom-update in the Terminal will tell you which version of firmware is running.

PCIe 3 Mode

To enable experimental and not-officially-supported PCIe 3 mode, add the follow line to the [all] section at the end of your Raspberry Pi /boot/firmware/config.txt file like this:

[all]
dtparam=pciex1_gen=3

Save and reboot - your drive is ready to use!

Formatting the NVMe and booting from NVMe

If you want to boot from the NVMe drive, follow these extra steps:

1. Make sure your firmware is updated as above!
2. Format the drive using Raspberry Pi Imager
3. You can do this with your NVMe Base installed by booting the RPi 5 from SD card and running Raspberry Pi Imager from the start menu.
4. Open a Terminal (Ctrl-Alt-T).
5. Run sudo raspi-config
6. Choose NVMe/USB boot under Advanced Options > Boot Order.
7. Reboot your RPi 5.

Notes

• Always power off your RPi and disconnect the power supply before installing or uninstalling the NVMe Base.
• NVMe Base offers a general purpose PCIe x1 connection - while we know most people want to add fast storage in theory you can use other devices with it, we just can't help you make them work! :-D What Would Jeff (Geerling) Do?

Monitor your world with Enviro for Raspberry Pi! There's a whole bunch of fancy environmental sensors on this board, and a gorgeous little full-colour LCD to display your data. It's the perfect way to get started with citizen science!

Designed for environmental monitoring, Enviro  lets you measure air quality (pollutant gases and particulates*), temperature, pressure, humidity, light, and noise level. When combined with a particulate matter sensor*(not included), it's great for monitoring air quality just outside your house (more information below), or without the particulate sensor you can use it to monitor indoor conditions.

Enviro  is an affordable alternative to environmental monitoring stations that can cost tens of thousands of pounds and, best of all, it's small and hackable and lets you contribute your data to citizen science efforts to monitor air quality via projects like Luftdaten.

Features

• BME280 temperature, pressure, humidity sensor (datasheet)
• LTR-559 light and proximity sensor (datasheet)
• MICS6814 analog gas sensor (datasheet)
• ADS1015 analog to digital converter (ADC) (datasheet)
• MEMS microphone (datasheet)
• 0.96" colour LCD (160x80)
• Connector only for particulate matter (PM) sensor*(sensor is included)
• pHAT-format board
• Fully-assembled
• Compatible with all 40-pin header Raspberry Pi models
• Pinout
• Python library
• Dimensions: 65x30x8.5mm

A couple of nice little extras... there's a spare ADC channel broken out on a header if you want to connect another analog sensor, along with I2C pins in the right configuration for plugging one of our Pimoroni I2C breakouts onto!

Citizen science air quality monitoring

We've developed this board in collaboration with the University of Sheffield, with the aim of letting you contribute real-time air quality data from your local area to open data projects like Luftdaten.

The alarming drop in our air quality is something that's really important to understand. Devices like Enviro  allow fine-grained, detailed datasets that let us see shifts in air quality through time and across different areas of cities. The more devices that contribute data, the better quality the dataset becomes.

Particulate matter (PM) is made up of tiny particles that are a mix of sizes and types, like dust, pollen, mould spores, smoke particles, organic particles and metal ions, and more. Particulates are much of what we think of as air pollution. They can be measured, in size and quantity, by particulate matter sensors like the PMS5003 that you can connect to Enviro .

The analog gas sensor can be used to make qualitative measurements of changes in gas concentrations, so you can tell broadly if the three groups of gases are increasing or decreasing in abundance. Without laboratory conditions or calibration, you won't be able to say "the concentration of carbon monoxide is n parts per million", for example.

Temperature, air pressure and humidity can all affect particulate levels (and the gas sensor readings) too, so the BME280 sensor on Enviro  is really important to understanding the other data that Enviro outputs.

We've got a tutorial (coming soon) that shows you how to use Enviro  and a few easily-available bits to build the board into a weather-proof housing that you can mount outside your house to monitor local air quality.

Indoor monitoring

As well as outdoor air quality monitoring, Enviro  is really good for indoor monitoring too. The temperature, humidity, light, and noise readings can be used to keep track of conditions in your home and, combined with the LCD to display the data and the proximity sensor for interaction, it makes an ideal headless monitoring device.

Why not combine it with some IoT smarts like an Alexa skill so that you can ask what the temperature or humidity is? Or you could set up a trigger action with IFTTT that turns your Philips Hue lights on when the light level drops below a certain level. There's loads of possibilities!

Software

We've put together a Python library to control all the parts of your Enviro . There's a bunch of examples for each of the individual parts, an all-in-one example that shows you the data from Enviro 's sensors in a visual way. There's also an example that shows you how to contribute data to Luftdaten (requires particulate matter sensor).

Getting started

Have a read through our (exhaustive!) Getting Started with Enviro  tutorial that walks you through how to install the software, how to run the code examples, and how to use the Enviro  Python library.
