I've made my first schematic for a sensor fusion PCB based on ESP32-H2. I'd like to get feedback on: Overall schematic, Specifical feedback on the following: Is the EN(Pin 8) pin energised correctly? Are the TXD0 (Pin 31) and the RXD0 (Pin 30) needed to "flash" the firmware...
While reviewing the ESP32-S3 Hardware Design Guidelines document, I noticed that in the RF section, the reference schematic shows additional LC components after the Pi network. I have not seen an inductor and capacitor in series with each other connected between the RF and Ground pin in any ...
shows the schematic of components connected to pin47 CAP2 and pin48 CAP1. C5 (10 nF) that connects to CAP1 should be of 10% tolerance and is required for proper operation of ESP32. RC circuits between CAP1 and CAP2 pins may be omitted under certain conditions. This circuit is used w...

schematic or even a good, written description) Former refused to work till the end (mounting the SD card fails every time), the SD Card reader worked and works fine from the start if one does NOT attempt to use 3.3V. When I find time, I will dug deeper into the issue and come back...
(This schematic uses the ESP32 DEVKIT V1 module version with 30 GPIOs – if you’re using another model, please check the pinout for the board you’re using.)Note: You can use any pin you want, as long as it can act as an output. All pins that can act as outputs can be used...

Aside from that, I don't really see an issue with your schematic... perhaps it's worth reading out the U0TXD pin to see what the bootup chatter looks like?norwegian Posts: 5 Joined: Mon Nov 14, 2022 8:12 pm Re: ESP32-S3 DFU/Programming by norwegian » Sun Nov 20, 2022 7:...
