Drive up to 16 RC servos with rock-solid 12-bit PWM over I²C. External 5–6 V power input, per-channel headers, and address jumpers so you can stack multiple boards.
Highlights
-
16× independent PWM channels (12-bit, ~0.98 µs resolution)
-
I²C control (default 0x40; address jumpers to stack up to 62 boards)
-
Onboard oscillator (~50–1000 Hz; 50–333 Hz typical for servos)
-
External 5–6 V servo rail with screw terminal
-
Works with Arduino / RP2040 / ESP32 / STM32 libs out of the box
