When building a drone, space and weight are critical considerations. Most commercial ESP32-CAM modules feature a double-stacked design that complicates packaging and includes unnecessary features for aerial applications. This custom-designed board addresses these limitations with a compact, flat, single-stack PCB optimized for drone integration.
- ESP32-WROOM-1U Module
- Native 8-bit camera interface
- External antenna for extended range
- Built-in USB flashing (eliminates USB-to-UART converter requirement)
- 40-Pin FPC Connector for OV2640 camera module
- Integrated 5V to 2.8V and 5V to 1.8V LDO regulators for camera power
- USB-C Port for programming and debugging
- GPIO Expansion - All GPIO pins exposed via headers
- Flexible Power Options
- USB-powered or external 5V supply
- Reverse current protection via Schottky diode
This board can be manufactured through JLCPCB with their PCB Assembly (PCBA) service. The bill of materials is provided below, and the complete PCBA BOM is available at Output/JLC_BOM.xlsx.
Note: The ESP32-WROOM-1U module must be purchased and soldered separately, as it cannot be included in the standard JLCPCB PCBA service.
