Introduction

The Nyboard V1 used by robot uses the Atmel ATMEGA328P controller, which only supports only one serial port. We separate the serial port of Nyboard to support more modules. The pins of the serial port are compatible with the 6-pin Arduino Pro Mini. Pin definitions are shown in the table below:

The default serial baud rate is 115200bps.

There're 3 communication modules for the NyBoard V1:

• USB uploader

• Bluetooth dual mode（EDR & BLE）JDY-23

• WiFi module ESP8266
