ESP32-C3 24 pinn FPC epaper controller with touch Rel 1.1 review
martinberlin opened this issue · comments
The goal of this issue is an effective PCB review by GOOD DISPLAY and by independent interested parties. All KiCAD files can be found here:
https://github.com/martinberlin/H-spi-adapters/tree/master/C3-27-epaper-touch
For any other PCB creations I will make sure to check the bootloader and other important MCU design guidelines (This costed me a failed Rev 1.0)
Other important notes and pin configurations:
- Touch INT is also shared w/ IO8 which needs to be high in order for MCU to enter download mode. (So it needs to have a 3.x K resistor or you can't flash it, otherwise I will put a 10K resistor but it won't work)
- RTC INT alarm output is also offered as an external GPIO with the advice that is RTC INT and has a 10K pullup resistor.
PCB Preview in front copper and back, plus silkscreen and front 3D view (has only 2 layers to make it cheaper)
Working. NOTE: This project stays here for historical reasons but now the switch idea has it's own repository
