An esp32 development board that uses 0805 and sop packages for worry-free hand soldering and has been verified
The circuit filtering and decoupling redundancy is sufficient
It has the same specifications as the best-selling esp32 development board. Each component has a value printed on it. I believe everyone can distinguish between resistors and capacitors.
The power supply uses ry3415buck chip, and the serial port uses ch9340k.
In the actual circuit, the anti-bounce capacitor of the boot button in the lower right corner needs to be very small or not added, otherwise it will affect the power-on sequence.
ch9340k has very low voltage requirements. The decoupling capacitor can be left unsoldered or increased to uF level.
The feedforward capacitor is recommended to be 22pF
There are Type-C on the front and back, but it is recommended to use the reverse side.
