4-40pin LCD MCU universal test board V2.1

1. The purpose of the circuit is mainly to test the quality of the LCD screen.

2. The circuit contains common capacitors to ground, C2C capacitors, resistors to ground, and resistors to VDD. They can be used after connecting them with Dupont wires to avoid repeated desoldering.

3. The circuit contains a 5, 9, and 12V switchable auxiliary power supply for multi-string backlight drive, or display chips that require a separate high-voltage power supply.

4. For 0.5mm and 1mm fpc, the FH26W-15S-0.3SHW BM20B(0.8)-24DS-0.4V interface has a finished base and can be directly connected for testing without soldering.

5. The screen with 2.54 DuPont interface can be tested directly without welding.

6. For 0.6.7.8.9mm fpc screen, in most cases only the FPC is needed to be soldered, and the rest are connected with Dupont wires.

7. There are two minimum microcontroller systems, namely Nuvoton's MS51 (compatible with 76E003) and STC8H. You can debug and download by plugging in NULINK and STCLINK.

8. Supports 40pin interface. Each interface has quick soldering positions for ground and VDD. Under special circumstances, chip components can be short-circuited or soldered. In most cases

You can do it with Dupont wire.
