From the project

F\~ishPV is a open source, custom stack, 75mm tinywhoop drone design. It utilises AM32 for the ESC firmware and Betaflight for the flight controller.

F\~ishPV is a open source, custom stack, 75mm tinywhoop drone design. It utilises AM32 for the ESC firmware and Betaflight for the flight controller.

Custom components include a from-scratch frame, designed for 3d printing (in HP-12-CF filament), a fully custom 15A ESC, and a custom FC.

The ESC: - 15A Continuous - 20A Peak for 5s (unverified :O) - 2S Battery (only) - AM32 Firmware - DSHOT Communication + Voltage telemetry - Current Sense

Esc: common questions

How big is the Esc PCB?

The Esc measures 28.3 × 28.3 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Esc?

132 components, from 21 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Esc design files?

From the cookiemonsternz/drone repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Esc design in my own project?

The repository has no license, so all rights stay with cookiemonsternz. Use it as a reference, and ask the author before reusing the design.
