big size industrial-grade 3.37-inch OLED display module ,Green and yellow font color optional

Description:

The big size 3.37-inch OLED display module uses 32-bit RSIC-MCU, can be directly connected to MCUs with serial interfaces such as UART/RS232/SPI (such as 51 microcontrollers, AVR, PIC, DSP, ARM, industrial computers, etc.). The user only needs to send a simple command to the terminal through the serial port to realize the drawing and display functions, and there is no need for tedious calculations and operations in the user code.

main features:
1. The factory presets the font library, which supports GB2312 series font library (12x12, 16x16, 24x24, 32x32 Chinese characters)
and ASCII codes (6x12, 8x16, 12x24, 16x32 characters);
