Toshiba has teamed up with MikroElektronika to create motor drive modules in one of Mikroe’s interchangeable standard PCB formats – Clicker 4 in this case.
“Mikroe Clicker 4 development board for Toshiba’s M4K MCU, combined with the Clicker 4 Inverter Shield is a solution for experimenting with brushless dc motor control,” according to Toshiba.
Clicker 4 for TMPM4K is built around a 32bit Arm Cortex-M4 TMPM4KNFYAFG MCU running at up to 160MHz with vector engine, encoder and programmable driver for brushless dc motors. THere is als0 256kbyte code flash, 32kbyte data flash and 24kbyte of SRAM.
Functional expansion is through four mikroBus sockets for adding Mikroe Click boards, and there is an on-board debugger as well as extension connectors, JTAG/SWD debug ports, LED indicators and push buttons.
Clicker 4 Inverter Shield clips underneath the processor board and has six mosfets to mediate power between an external 12 to 48V supply and the motor, and a TI DRV8323 gate driver. An on-board switching power supply produces a 5V output for the controller board.
“Over-current protection has been incorporated for assured reliability,” said Toshiba, adding that the board’s “interfacing allows positioning feedback to be obtained from Hall sensors and incremental encoders.”
Software support comes from Toshiba’s ‘MCU motor studio’ which has two main components: configurable motor control firmware for the M4K MCU, plus a PC-based tool that allows parameter configuration, drive control, real-time logging and diagnostics via UART.
