We are developing a prototype of a consumer device.
For it, we planned to use ESP32 and need to make prototype board for it.
The board must be the standard Arduino Uno size, so the result PCB will be like WeMos D1-R32 board.
Standard Arduino connector for mounting Arduino shileds like TFT LCD panel
CH340 (or FT232)
One OP amp (TLC272)
One Multiplexer (74LV4051)
One Low-gain Amplifier (MCP6S22)
2-pin connector for Photodiod
6-pin connector for digital light sensor module OPT3001
Bonus: it would be great if possible to include li-ion battery chaging and to-5V boost up circuit
If the prototype works well, we're willing to order production PCB to the same designer with more budget.
The budget of this prototype PCB design is $150.
Please do not make my time wasted if you want much bigger budget than $150.
