Kv4p HT
Kv4p HT is an open source ESP32 PCB design by VanceVagell: a 4-layer, 80 × 47 mm board with 87 components (43 distinct parts). It is built around the AZ1117H-3.3TRG1, CP2102N-A02-GQFN24, ESP32-WROOM-32E-N4. Filed under rf & radio.

Use Chrome. For some reason, the JLCPCB order process is broken for me on FireFox. Much sadness.
You'll need the following three files: *
Go to Click: "Add Gerber," and upload https://github.com/VanceVagell/kv4p-ht/blob/main/pcb/KiCAD/kv4p-ht/production/kv4pHT2.0c.zip * JLCPCB will ask you a bunch of questions about the file. The auto-loaded defaults are sufficient, but if you know you want to change something (solder mask color, etc) do it here.
