DrikrAIO
About the DrikrAIO PCB
DrikrAIO is an open source ESP32 PCB design by tetraethylmethane, published on GitHub. It is a 6-layer board measuring 50 × 50 mm, with 339 components from 90 distinct parts.
Its main chip is the ESP32-C3, from the ESP32 family. Other key parts include the RP2354A, TS2306A 240gf MSM 9, LP5912-1.8DRVR, LMR51430YFDDCR and LP5912-3.3DRVR. By type, the board carries 119 resistors, 104 capacitors, 36 connectors, 27 ICs, 26 transistors and 9 diodes.
From the project
Single-board integration of a flight controller, four ESC channels and an ExpressLRS receiver, assembled from proven OpenDrone designs.
Single-board integration of a flight controller, four ESC channels and an ExpressLRS receiver, assembled from proven OpenDrone designs.
Status: schematic netlists; board is a placed scaffold, unrouted. See Open work.
This is Stage 1 of two. It deliberately targets FPV-class hardware on the parts that already fly, to prove the integration once. Stage 2 re-platforms to ArduPilot on a Pixhawk Autopilot Bus carrier and reuses the power tree, ESC block and layout zoning proven here.

DrikrAIO: common questions
What microcontroller does the DrikrAIO use?
The DrikrAIO is built around the ESP32-C3, from the ESP32 family.
How big is the DrikrAIO PCB?
The DrikrAIO measures 50 × 50 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the DrikrAIO?
339 components, from 90 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 DrikrAIO design files?
From the tetraethylmethane/NIDAR-RescueSwarm 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 DrikrAIO design in my own project?
The repository has no license, so all rights stay with tetraethylmethane. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the DrikrAIO without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
