Introduction

"XBoard NANO development board" is a series of development boards with different main controls (100pin and smaller microcontrollers) but consistent appearance and pin functions. The main purpose of this series of development boards is inter-board communication protocol testing (development board + development board) , Single module test (development board + evaluation board)

"XBoard NANO Development Board" consists of a carrier board and a core board, which are connected through the M2 E Key interface. This project is the carrier board part of the "XBoard NANO Development Board".

Some core boards:

This series of development boards are not pin-compatible with the front-end series "XBoard Standard Development Board" (obsolete)
