Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE) SF_RFID Tags Connect to it with any

Connect to it with any microcontroller over SPI and read out the resistance ratio from the internal ADC

the absolute limit for the MOSFETs

Important: Due to global supply chain issues with some of the parts included in the SIK v4

This is an Arduino-compatible board with integrated 3W stereo amplifier designed for use in arcade projects (like our Picade)

This allows you even more options to balance performance with power consumption over the original ESP32
