I also powered the board independently instead of attaching it to my PC and still the same result. On very low power settings i can also see that all 3 color leds are powered, the red one is just brighter than
The power and charge LEDs and corresponding resistors drain the battery, so they've been isolated to the 5V power domain so they will only light up and draw power when the board is either being powered by the USB connector, or by a 5V power source connected to the 5V header pin. ...

If this is what you see on the LEDs, the board should be ready for application upload. Now prepare the PC by loading and configuring development tools what is discussed in the next section. 如果指示灯如上述显示,则初始设置已经完成,开发板可用于下载应用程序。现在,请按下文介绍运行并配置 PC 上...

“Upper layer” main development board contains ESP32-PICO-D4 SiP, battery connector & charger circuit with LiPo charge status LEDs, Reset & pull-up IO0 buttons, and a green LED on GPIO4. “Lower layer” board has the USB connector and functions as a USB to UART bridge. Size: 17 mm...
I've recently build my own dev board utilizing the ESP32-C3-MINI-1-N4 module. Everything works pretty well and just as expected, I can control a few onboard LEDs just fine and upload code and everything. The only (major) problem is that I apparently can't receive any Serial data. ...
