RA MCU experience ruler

RA MCU experience ruler

RA MCU experience ruler size: 9.9 x 3.56 cm.

Main control chip: R7FA2E1A72DFL, R7FA2L1AB2DFL, etc. (chips can be purchased at Taobao RA Ecological Studio).

Introduction: This experience ruler is mainly used to learn and experience RA MCU. The resources have been marked on the board and can be soldered and used without looking at the schematic diagram.
