RCM old code for the original boards
useful bits of code are here
- useful code for using RCM V4s
- useful code for using BYTEs
- useful code for using Nibbles
- useful code for using original RCMs
- useful code for using RCM D1s
RCM 1, 2, and 3 the originals
- 4 motors
- 5 servos
- battery monitoring
- runs from 5 NiMH AA batteries
- all components are hand-solderable through-hole parts
- get printed circuit boards ("V3") or build by hand from a perf board ("V1")
RCM 4 a better through-hole hand-solderable RCM
- 2 x 3 inches, 50.8 x 76.2 mm
- 4 motors and 7 servos OR 6 motors and 3 servos
- runs from 5 NiMH AA batteries OR (need to test) 4.5-20v with the addition of voltage regulators
- all components are hand-solderable through-hole parts
- Qwiic-Compatible
RCM BYTE a smaller yet more capable design
- about 1.25x1.25 inches
- 8 motors
- 8 servos
- battery monitoring
- I2C connector on QT PY
- runs on 3-11 volts
RCM NIBBLE it's half a BYTE
- about 1x1 inches
- 4 motors
- 4 servos
- 2 additional GPIO pins
- built-in IMU
- battery monitoring
- I2C connector on QT PY
- runs on 3-11 volts
RCM D1 lowest cost RCM
- 1.75 by 1.575 inches, 44.45 by 40.0 millimeters
- 2 motors (one L293D)
- 2 servos OR qwiic connector
- Qwiic-Compatible
- runs on 4 NiMH AAs
- battery monitoring
- uses a Wemos D1 mini with esp8266 CPU
- Reads 8 quadrature encoders
- 1.0x0.85 inches
- I2C (Qwiic Compatible)
- powered by an ATMega328PB
- hand solderable surface mount components
