C51 Development Test Board

Monochrome COG/Graphic COB/Character COB/OLED module/E-paper module/Segment screen 8051 test board

Core Function: It is used for testing display devices such as monochrome COG, graphic COB, character COB, OLED modules, E-paper modules, and segment screens. Based on the 8051 single-chip microcomputer architecture, it supports the connection and debugging of OLED screens with I2C and SPI interfaces.

Hardware Composition: It is equipped with an STC series single-chip microcomputer chip, a reset button, a crystal oscillator circuit, a power interface (supporting 5V and 3.3V power supply), OLED interfaces (OLED-I2C and OLED-SPI), various electronic components (resistors, capacitors, diodes, etc.), and a USB interface for power supply or program download.

Application Scenarios: It is mainly for learners or developers in the fields of electronic engineering and embedded development, and is used for single-chip microcomputer program development, display module drive testing and other experiments and project development, helping users quickly verify the control logic of 8051 single-chip microcomputers on various display devices.
