Very similar to the wESP32-Prog, which I bought a while back for programming my own esp32-based board without having to get the programming circuitry correct myself. One neat trick the wESP32 does is to use a staggered row of through-holes on the board to be programmed so that the male pin headers on the programming module can be inserted into the PCB directly and usually make good-enough contact with the pins to program the board without requiring a part to be installed.
I built one of these a while ago, and its really handy. Have just designed a new version that uses an ESP32S3 as its cheaper than the serial chip I was using, but still lets me do serial flashing exactly the same, but with scope for flash via wifi or using wifi for console when debugging
Very nice, makes it much easier to flash commercial devices with new firmware!

Nice!
Any ESP devboard with an onboard USB2UART bridge chip can be used as a serial programmer.
At the risk of sounding like a bot: cool!
