Hargrave nanoDRIVE 4LPi 4-in-1 ESC
Hargrave Technologies' NDAA-compliant nanoDRIVE 4LPi 4-in-1 ESC combines four UAV motor controllers on a single 20 g board, simplifying multirotor power and signal wiring. Each channel is rated for 20 A continuous current and 40 A peak current, with a 7 to 25 V recommended input range and an integrated 5 V, 2.5 A BEC.
The controller can use the FOCAL field-oriented algorithm or trapezoidal commutation and accepts standard or bidirectional DShot150 to DShot600 and servo PWM inputs. DroneCAN provides control, telemetry, and firmware updates, with ARINC 825 support identified for a future firmware release.
Additional functions include regenerative braking, configurable switching from 4 to 64 kHz, and CAN, serial, and PWM telemetry.
