Now look at this cutest little microSD card reader/writer - but don't be fooled by its compact size! It's wicked fast and supports up to 128 GB SDHC cards! Simply slide the card into the edge, and plug it into your computer's USB port. No drivers are required, it shows up as a standard 'Mass Storage' device under any OS.

It comes with a handy little cord so you can attach it to your datalogger project. It also has a little plastic cover for the USB A connector part so it won't short against nearby electronics.

Max read speed is 16 MB/sec, max write speed is 6 MB/sec - most microSD cards are not this fast so the bottleneck will be the card, not the reader.

Interfacing with a relay

As announced Raspberry Pi 4 model B has upgraded the power input port to USB-C and you will need this cable to power it. Although it is terminated with USB-A 2.0, the power wires (VUSB and GND) have thicker gauge and we have tested it. This cable can delivers up to 2.5A to Raspberry Pi 4 model B.

Supporting USB 2.0 speeds and charging up to 2.5A, this 1 meter cable is perfect for embedded enthusiast that need the flexibility of a good cable and the wonderful feel of a reversible USB-C & USB-A connection. It is perfect if you want to boot up Raspberry Pi 4 Model B from a laptop. Not to forget to connect microcontroller development board like M5Stack.

This cable has the D /D- wires along side large-gauge VBUS/GND wires. Although it is rated for 2A, we've successfully pulled 2.5A@5V with minimal voltage drop.

If you have ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be! The logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. Each level converter can convert 4 pins on the high side to 4 pins on the low side, with power supply pins on each side.

The usage of the level converter is very straightforward. The board needs to be powered from the two voltage sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the "HV" pin, low voltage (3.3V for example) to "LV", and ground from the system to the "GND" pin.

This module requires you to supply it with power from both the higher voltage level and the lower voltage level. Connect the higher voltage source to pin "HV" and its ground to pin "GND" near the "HV" pin. Also, connect the lower voltage source to pin "LV" and its ground to pin "GND" near the "LV" pin.

For example, if you were connecting your Arduino (5V signals) to an ESP8266 (3.3V signals), you would connect the "HV" pin on the module to the 5V supply pin on your Arduino and the "GND" pin near the "HV" pin to the "GND" pin on your Arduino. Then, you would connect the "LV" pin on the module to the 3.3V power source that is supplying power to the ESP8266 and connect the "GND" pin near the "LV" pin to the 3.3V power supply's ground. You would then connect the signal pin from your Arduino to one of the signal pins on this module (for example, pin "HV1"), and then you would connect the desired signal pin on the ESP8266 to the corresponding pin on this module ("LV1" if the higher voltage signal is connected to "HV1").

These are 4 Channel devices (works great for I2C or SPI) and will work with all microcontrollers, Arduino, Raspberry Pi, Intel Edison, etc. Use this module to connect two devices of different digital voltage levels. For example: connecting an Arduino (5V device) to an ESP8266 (3.3V device).

The logic level converter comes complete with header pins and can be used directly on a breadboard.
