ESP32-S2 WROOM Module with PCB Antenna – 4 MB flash and no PSRAM – 4MB Flash

The ESP8266 started a small revolution by bringing WiFi to a small and cheap package that also had enough processing power and enough pins to get small things done. Then the ESP32 came out with tons of pins, Bluetooth support, and dual 240 MHz cores. Now get ready to take your IoT designs to the next level with the ESP32-S2-WROOM WiFi Module!

Adafruit ISO1540 Bidirectional I2C Isolator – STEMMA QT / Qwiic

Sometimes you’ll find yourself with an I2C bus controller on one side, and an I2C bus device on the other and you gotta keep em (electrically) separated. Maybe because one is Earth-grounded, maybe because you’ve got some funky power monitoring setup, maybe you want to reduce noise.

Whatever it is, you can use the Adafruit ISO1540 Bidirectional I2C Isolator to add full electrical isolation between two sides of an I2C bus. The chip we use, the TI ISO1540 is fully bi-directional, supports up to 1 MHz clock rates, supports clock-stretching, works with 3 to 5V DC power or logic (separate on either side of course), with 2500 V-RMS isolation

STEMMA QT / Qwiic JST SH 4-Pin Cable – 50mm Long

This 4-wire cable is 50mm / 1.9″ long and fitted with JST SH female 4-pin connectors on both ends. Compared with the chunkier JST PH these are 1mm pitch instead of 2mm, but still have a nice latching feel, while being easy to insert and remove.

This cable can be used with Qwiic or STEMMA QT boards, to easily connect sensors and drivers from one board to the other. The cables are made symmetrically so don’t worry about which side goes where!

OBD Plug (16-pin) to DE-9 (DB-9) Socket Adapter Cable – 1 meter long

Not to be confused with ODB, OBD stands for On Board Diagnostics and is used for analyzing and diagnosing vehicles. It’s the thing your mechanic plugs into to find out why you’ve got a blinking engine light.

Technically, OBD uses CAN bus and, hey, whaddya know, we’ve got some CAN-capable microcontroller boards here at Adafruit so this OBD Plug (16-pin) to DE-9 (DB-9) Socket Adapter Cable will come in super handy when you want to attach one of our CAN boards to your car!

On one end is a 16-pin OBD plug that goes right into your car’s port. The other end is a DE-9 ‘CAN bus’ connector. Sometimes DE-9 connectors are referred to as DB-9. Technically that’s the wrong name, but it’s so ingrained that most people only know the connector as DB-9.

Note: Despite having a serial port-looking end, this cable is not meant to be plugged directly into a computer’s serial port. It is meant to plug into a hardware CAN BUS interface. It does not contain circuitry or any kind of translator, it only re-wires a OBD plug into a DB-9 plug

Adafruit AW9523 GPIO Expander and LED Driver Breakout – STEMMA QT / Qwiic

Expand your project possibilities, with the Adafruit AW9523 GPIO Expander and LED Driver Breakout – a cute and powerful I2C expander with a lot of tricks up its sleeve.

GPIO expanders work like this: you have a board with some number of GPIO but not enough for your project – maybe you need more buttons or LEDs. You could upgrade to a board with massive number of GPIO like the Grand Central, or you could pop on one of these boards. Connect it over I2C and then you can send/receive I2C commands to control the GPIO pins to write and read them. It’s going to be slower than direct GPIO access, but maybe that doesn’t matter if it takes a millisecond instead of a microsecond. You only need the two I2C pins, and you can even share the I2C port with other sensors and devices. Heck, you can even add more expanders for massive I/O control!
