Re: esp32-c3_hardware_design_guidelines_cn 中原理图的疑问点:by LJH » Tue Oct 19, 2021 8:43 am 因为GPIO2 是 strapping 管脚,SPI boot 和 UART boot 上电都需要为高,所以就直接加了个上拉电阻。plj_357 Posts: 11 Joined: Fri Oct 15, 2021 8:52 am ...
One board is Wemos C3 Picohttps://www.wemos.cc/en/latest/c3/c3_pico.html; I tried two different crystals, different capacitors, tried to put a resistor in parallel (though the hardware design guidelines document says it must not be needed) - nothing helped. ...

ESP32C3 custom board Device Description Custom ESP32C3 board ; The ESP32C3 is only connected to USB-C port, two 74HCT245D buffers (inputs only) and a tact switch (details below). This ESP32C3 design block, which follows the hardware design guide, has already been used in several boards...
After reviewing the hardware design guide again, I didn't find any issues with the layout. So I thought of using a new module, without soldering it to the board, to directly connect 3.3V and GND with the power supply, connect EN to pull up, measure IO0 directly with an external meter...
