Hardware for BBC micro:bit WiFi bridge

Hi All, I have done a schematic for the BBC micro:bit WiFi bridge. It is based on the ESP12. I would like to make it as open-source hardware. Can someone help me to review the circuit? Thanks.

If that’s a dual layer PCB, I’d try to route as much as possible on Top layer and make the Bottom layer possibly solid ground plane. I’d also place some decoupling caps near the ESP module. It’s just general recommendation, not a review of your particular circuit.
