Its main chip is the ATMEGA4808-AFR, from the AVR/Arduino family. Other key parts include the NRF24L01P-R, DRV8212DSGR, BMP390L and TPS7A2030PDBVR. By type, the board carries 28 capacitors, 13 resistors, 8 ICs, 3 inductors, 1 transistor and 1 crystal.

It belongs with the robotics & motion, rf & radio and sensors designs in this gallery.

From the project

Electronics and software for a mini RC helicopter

I had to learn alot for this project, as there were several things I had no experience with such as the radio transceiver circuitry. In the end, it turned out well and was very fun to make.

Overall, I'm happy with the result and wouldn’t hesitate to use PCBWay again in future projects. If you’re looking for a PCB manufacturer that’s reliable, responsive, and produces high-quality results, they’re worth checking out.

Heli avionics: common questions

What microcontroller does the Heli avionics use?

The Heli avionics is built around the ATMEGA4808-AFR, from the AVR/Arduino family.

How big is the Heli avionics PCB?

The Heli avionics measures 65.5 × 39 mm, has 4 copper layers and is 1.57 mm thick.

How many components are on the Heli avionics?

56 components, from 32 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 Heli avionics design files?

From the 1-max-1/heli-avionics 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 Heli avionics design in my own project?

The repository has no license, so all rights stay with 1-max-1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Heli avionics without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
