Seeeduino Lotus v1.0 

 

Introduction 

Seeeduino Lotus is an ATMEGA328 Microcontroller development board. It is a combination of 
Seeeduino and Base Shield. It used Atmel ATMEGA328P-MU and CH340. ATMEGA328P-MU 
is a high performance, low power AVR 8-Bit Microcontroller. CH340 is an USB bus converter 
chip that can realize an USB to serial interface. Seeeduino Lotus has 14 digital input/output (6 of 
which can output PWM) and 7 analog input/output, a micro USB connection, an ICSP header, 12 
Grove connections, a reset button.
