Rotini-Hardware

Rotini is the smallest all-in-one melty brain control system in the world! Rotini has voltage regulation (BEC), reverse polatiry protection, high power LED driving, an ELRS transceiver, and inertia sensing. All controlled by an ESP32-S2 MCU.

Rotini Features

• ESP32-S2 MCU has processing power to spare, even running the arduino core
• 400g H3LIS331DL Accelerometer is rotated 45 degrees for increased precision
• ESP8285 with SX1280 LoRa transceiver run ELRS 3.0.0 providing reliable wireless communication
• SY8253ADC switching regulator provides up to 1A at 3.3V. Maximum input voltage of 27V!
• USB-C port provides swift and robust serial programming interface

Manufacturing

⚠️ Beware: we offer these files without warranty of any kind, express or implied. Use them at your own risk.

Rotini can be entirely manufactured and assembled by JLCPCB! They will need the gerber, BOM, and pick-and-place files found in this repo. The one caveat is JLC does not have a 400g accelerometer in their library. You will need to order H3LIS331DL via JLCPCBs global part sourcing system well before ordering your boards.

Possible features for V4

• TVS diode protection for GPIO pins (including LED drivers)
