Description:
A postage stamp sized RP2040 development board with a USB-C connection and 8MB of flash, perfect for portable projects, wearables, and embedding into devices.
While we love the Raspberry Pi Pico we also wanted something smaller and with a bunch more flash on board. Introducing the Tiny 2040 - a teeny tiny powerhouse with the chops to realise truly ambitious projects.
Powered and programmable via USB-C, Tiny 2040 comes with 8MB of QSPI (XiP) flash on board so it can handle projects small and large with ease. The board is designed with castellated pads to allow it to be directly soldered onto a PCB or alternatively you can use pin headers to hook it up on a breadboard or directly with wires. We've even managed to fit in a programmable RGB LED, a reset button and some clever circuitry that lets you use the boot button as a user controllable switch.
It's compatible with firmware built for the Raspberry Pi Pico but offers a reduced number of pins due to its size. You can even run MicroPython on it!
Features
- Powered by RP2040
- ARM Cortex M0 running at up to 133Mhz
- 264kB of SRAM
- USB-C connector for power, programming, and data transfer
- 8MB of QSPI flash supporting XiP
- User controllable RGB LED
- Twelve IO pins (including four 12-bit ADC channels)
- Switch for basic input (doubles up as DFU select on boot)
- On-board 3V3 regulator
- Dimensions: approx 22.9 x 18.2 x 6mm (L x W x H)

About RP2040
Raspberry Pi's RP2040 microcontroller is a dual core ARM Cortex M0 running at up to 133Mhz. It bundles in 264kB of SRAM, 30 multifunction GPIO pins (including a four channel 12-bit ADC), a heap of standard peripherals (I2C, SPI, UART, PWM, clocks, etc), and USB support.
One very exciting feature of RP2040 is the programmable IOs which allow you to execute custom programs that can manipulate GPIO pins and transfer data between peripherals - they can offload tasks that require high data transfer rates or precise timing that traditionally would have required a lot of heavy lifting from the CPU.

Description:
This is an official Raspberry Pico that has had headers professionally pre-soldered on by a South African electronic manufacturing company.

Description:
PGA2040 is a compact RP2040 breakout intended for the most svelte and embeddable of projects. It contains only the components necessary to run the RP2040 (that's the crystal, flash, regulator and essential support circuits) and it has no fripperies like LEDs, buttons and USB connectors - you'll need to attach your own USB connector to be able to program it.
The benefits of all this drastic pruning are a tiny, 21mm square footprint and lots of exposed RP2040 pins to play with! 30 of them can be used as general purpose I/O (that's four more I/O than on a Raspberry Pi Pico) and 4 are ADC-equipped. It also has the cutest little pin labels in the known 'verse, because space is tight on this board.
Header pins are sold separately - you can solder it to standard Pico pin headers (though bear in mind you'll need 48 pins if you want to populate it fully).
Like our other RP2040 boards, PGA2040 is programmable with C , MicroPython or CircuitPython - choose your fighter!
Specifications:
- Powered by RP2040
- Dual ARM Cortex M0 running at up to 133Mhz
- 264kB of SRAM
- 8MB of QSPI flash supporting XiP
- Crystal oscillator
- On-board 3V3 regulator (max regulator current output 300mA)
- 48 pins, arranged with 2.54mm (0.1") spacing in a Pin Grid Array
- 30 multi-function General Purpose IO (4 can be used for ADC)
- 8 GND pins
- Input voltage range 3V - 5.5V (on VB pin only)
- Measurements: approx 21mm x 21mm x 3mm (L x W x H)
- Schematic
- Eagle CAD part

1 x PGA2040


Getting Started :
PGA2040 is firmware agnostic! You can program it with C/C or MicroPython in the same way as you would a Raspberry Pi Pico. You can find (lots) more information on how to do that (as well as download links for the firmware/SDK) on the RP2040 landing page.
You can also use CircuitPython on your PGA2040! CircuitPython is an easy to use, well-established ecosystem with lots of example code and drivers for interfacing with different kinds of hardware. Click here to download the CircuitPython firmware for PGA2040 and click here for a getting started guide.
To program PGA2040 via USB you will need to hook wires up to VB, GND, U and U-. Make sure that the 5v only goes to VB on PGA2040, if it ends up elsewhere it will result in a bad time. A USB breakout board is a convenient way of getting at the wires in your USB cable, check out the extras tab for some options!
To get into BOOTSEL mode so you can flash firmware to your PGA2040, connect the BS pin to ground whilst plugging the USB into your computer.

Description
The WIZnet Ethernet HAT is a Raspberry Pi Pico add-on board that utilizes the W5100S embedded internet controller chip to provide an Ethernet connection to your Raspberry Pi Pico via SPI.
The board supports both 3.3V & 5V and can be mounted directly to your Pico as the HAT pinout matches the Raspberry Pi Pico pin footprint
About the W5100S Embedded Internet ControllerThe W5100S is an embedded Internet controller designed as a full hardwired TCP/IP with WIZnet technology. W5100S provides internet connectivity to your Pico by using SPI (Serial Peripheral Interface). SPI provides an easy connection via external MCU to W5100S. The clock speed of W5100S SPI supports up to 70MHz.
Since the W5100S integrates the hardwired TCP/IP stack with 10/100 Ethernet MAC and PHY, it is truly a one-chip solution for stable internet connectivity. WIZnet’s hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE - and it has been proven through various applications over the last decade.
The W5100S provides four independent sockets to be used simultaneously and 16KB internal memory for data communication. Users can develop an Ethernet application easily by using the simple W5100S socket program instead of handling a complex Ethernet Controller. W5100S also provides WOL (Wake on LAN) and a Power Down Mode in order to reduce power consumption.

Pinout

The W5100S-EVB-Pico pinout is directly connected to the GPIO of RP2040 as shown in the picture above. It has the same pinout as the Raspberry Pi Pico board. However, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, GPIO21 are connected to W5100S inside the board. These pins enable SPI communication with W5100S to use the Ethernet function.
If you are using the Ethernet function, these pins cannot be used for any other purpose.
The RP2040 GPIO used inside W5100S-EVB-Pico is as follows.
I/O | Pin Name | Description |
I | GPIO16 | Connected to MISO on W5100S |
O | GPIO17 | Connected to CSn on W5100S |
O | GPIO18 | Connected to SCLK on W5100S |
O | GPIO19 | Connected to MOSI on W5100S |
O | GPIO20 | Connected to RSTn on W5100S |
I | GPIO21 | Connected to INTn on W5100S |
I | GPIO24 | VBUS sense - high if VBUS is present, else low |
O | GPIO25 | Connected to user LED |
I | GPIO29 | Used in ADC mode (ADC3) to measure VSYS/3 |
Apart from GPIO and ground pins, there are 7 other pins on the main 40-pin interface:
Pin | Name | Description |
40 | VBUS | Micro-USB input voltage, connected to micro-USB port pin 1. Nominally 5V |
39 | VSYS | Main system input voltage, which can vary in the allowed range 4.3V to 5.5V, and is used by the on-board LDO to generate the 3.3V |
37 | 3V3_EN | Connects to the on-board LDO enable pin. To disable the 3.3V (which also de-powers the RP2040 and W5100S), short this pin low |
36 | 3V3 | Main 3.3V supply to RP2040 and W5100S, generated by the on-board LDO |
35 | ADC_VREF | ADC power supply (and reference) voltage, and is generated on W5100S-EVB-Pici by filtering the 3.3V supply |
33 | AGND | Ground reference for GPIO26-29 |
30 | RUN | RP2040 enable pin, To reset RP2040, short this pin low |

Raspberry Pi Pico W provides a minimal yet flexible external circuitry to support the RP2040 chip: flash memory (Winbond W25Q16JV), a crystal, power supplies and decoupling, and USB connector. The majority of the RP2040 microcontroller pins are brought to the user IO pins on the left and right edge of the board. Four RP2040 I/O are used for internal functions: driving an LED, on-board switch mode power supply (SMPS) power control, and sensing the system voltages.
Pico W has an on-board 2.4GHz wireless interface using an Infineon CYW43439. The antenna is an onboard antenna licensed from ABRACON (formerly ProAnt). The wireless interface is connected via SPI to the RP2040.
Pico W has been designed to use either soldered 0.1-inch pin-headers (it is one 0.1-inch pitch wider than a standard 40-pin DIP package), or to be positioned as a surface mountable 'module', as the user I/O pins are also castellated. There
are SMT pads underneath the USB connector and BOOTSEL button, which allow these signals to be accessed if used as a reflow-soldered SMT module.
