Documentation for Hardware and Software for my custom Flipper Zero module to connect a Heltec V3 LoRa ESP32 Dev board
FlipperZero Heltec is an open-source printed circuit board by hypernova256, from the hypernova256/FlipperZero-Heltec repository on GitHub. It is a 2-layer board of 64.8 × 30.5 mm with 2 parts on 29 nets, routed with 24 tracks and 0 vias.
It belongs with the radio and wireless boards of this library.
This is a GPIO expansion board to use the ESP32-based Heltec V3/V4 LoRa modules with the Flipper Zero. I decided to make this project as I was reluctant to purchase LiPo batteries for my Meshtastic/Meshcore modules, and will just use my Flipper for power instead. This board also contains serial communication for use as a regular ESP32 board.
Since these are ESP32 modules, they are compatible with ESP32 apps such as WiFi Marauder along with being Mesh networking modules.
This is my first PCB and CAD project, so feedback would be greatly appreciated.
I hope to make a 3D Printed case and possibly software such as a Meshtastic client for Flipper as well as possibly multi-booting the ESP32.
I have made a working prototype with a protoboard at my university makerspace and it works quite well!

It measures 64.8 × 30.5 mm and has 2 copper layers, 1.6 mm thick.
2 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the hypernova256/FlipperZero-Heltec repository on GitHub, at the commit this page was made from: the board is PCB/FlipperZeroHeltec.kicad_pcb and its schematic PCB/FlipperZeroHeltec.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask hypernova256 before reusing the design.
