EM-A24C-JS1 DC Motor Driver Module
EM-A24 is a DC-motor driver module, It's based on EM-241 driver card. This module is
PCB mountable and it needs a very small pcb area, because it will be installed vertically.
This module has effective H-bridge power stage. The power stage has low EMC emission
and it can meet EMC directives for industry and household enviroments without external
components. This big benefit when integrated this module to the "motherboard".
Module has two pwm frequency option 2kHz offer more current, and 16kHz is noiseless.
There is available various firmware version for this module This version EM-A24C-JS1
is specially for joystick use, and included for example three point calibration.
Firmware includes also many basic features for dc motor driver, like current limits,
stop and start ramps, and load compensation. The settings of device can be done
digitally with parameters. Firmware update can be done also with Ementool interface
