24) SIM808 UART configuration:

What's new

Some light soldering is required to attach the header but it is easy work for anyone with a soldering iron & solder

This board/chip uses I2C 7-bit addresses between 0x2E to 0x4D selectable by soldering jumpers on the back of the board

Arduino Leonardo (with headers) Brand_Gicren 24) SIM808 UART configuration:The classic Arduino board that can act as a mouse or keyboard. The Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). It has 20 digital input output pins (of which 7 can be used as PWM outputs and 12 as analogue inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a
