Which ESP32 board fits a small drone frame?
The SuperMini comes in C3, C6, S3, and H2 versions with WiFi and Bluetooth. Prices run from $9.99 to $17.99 by version.
The C3 SuperMini costs $10.99 and suits small IoT jobs. The S3 SuperMini costs $17.99 and suits camera and display work.
The S2 Mini costs $11.16 for a 1-pack with 4MB of flash and 2MB of PSRAM. It uses USB-C and works with MicroPython and Arduino.
Which board adds a camera to a drone?
The ESP32-CAM costs $25.99 with an OV2640 camera module and 4MB of PSRAM. It suits a first FPV video build.
The ESP32-S3-CAM board alone costs $11.97 with 16MB of flash and 8MB of PSRAM. Add an OV2640 camera for $23.12 in total.
Pick the OV5640 5MP camera version at $29.99 for sharper stills. Pick the OV2640 2MP version for faster video.
Which board gives WiFi telemetry?
The S2 Mini gives WiFi with 4MB of flash and 2MB of PSRAM for $11.16. It uses USB-C and works with MicroPython and Arduino.
The DevKit V1 gives WiFi and Bluetooth on a 30-pin WROOM-32 board. Its board versions cost $15.99 to $17.99.
Test the WiFi link at 2m from the router first. Move the drone farther only after the near link runs clean.
When should you pick the RP2040 instead?
The RP2040 Pro Micro gives a dual-core RP2040 chip with 16MB of flash for $8.37. It suits USB and sensor jobs.
The RP2040 board listing names no WiFi radio. Use it for wired jobs, and pick the S2 Mini for WiFi.
It runs MicroPython and QMK firmware with USB-C and BOOT and RESET buttons. That suits tiny drone add-ons.
How do you test a drone board on the bench?
Mount the board on the frame with standoffs or foam tape. Then power it from a stable 5V supply on the bench.
Load a test sketch and check each sensor reading. A sensor that works on the bench works in the air.
Test the WiFi link at 2m from the router before flight. A weak link on the bench fails faster in the air.
