1.44-inch TFTLCD expansion

1.44 inch TFTLCD module

• This time it is a 1.44-inch tftlcd display module. The corresponding program and usage methods will be placed in the attachment. It can be directly plugged into the expansion board for use.
• In addition to the screen itself, three independent buttons are also added. The buttons are connected in parallel with capacitors and have simple hardware anti-shake capabilities.
• Regarding the power consumption, I actually measured it and found that the current is about 70mA and the power consumption is about 0.2W, which is larger than the official 0.06W. The power consumption is relatively large, so if low power consumption is required, Still need to pay attention
• The screen uses a plug-in board, so it needs an FPC holder. Of course, it is better to use a welded one on the module. The schematic diagram should be similar, just change the PCB.
• This is a screen I bought before for 8 yuan with free shipping.~Return 5 yuan for good reviews~, hehe, but now the price has increased to around 14 or 15 yuan, so I’d better shop around as much as possible.
