I bought a few of these because I created a PCB with the ESP32 modules, but didn’t want to put the programming circuitry onto my board. I brought the RXD0/TXD0/GPIO0/EN(reset)/and ground to a connector and simply ran jumpers to this board. At first id didn’t work, but after I tried switching RX/TX it programmed and ran fine.
I recommend this board if you want to embed an ESP32 module in your design.

Ha. I came here to add what mhowarddune noted: you need to cross over TX and RX so that esp32 RXD0 goes to the programmer TXD, and esp32 TXD0 to programmer RXD. After I installed the CH340 driver and had it wired correctly, it worked on the first try. Just ordered a bunch more.
