RSS Bot Posted November 18, 2022 Posted November 18, 2022 We’ve already seen the Raspberry Pi RP2040 MCU in a 3D printer controller board, so it should come as no surprise that the dual-core microcontroller also found its way into a Pick-and-Place (PnP) machine control board. Designed by Thea Flowers, the Starfish board leverages the RP2040 MCU capabilities to control three Trinamic TMC2209 motor drivers, MOSFET drivers to control DC vacuum pumps, two vacuum sensors, and offer RS485 and I2C connectivity for feeders and peripherals respectively. Starfish specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller at up to 133 MHz with 264 kB of embedded SRAM Storage – QSPI flash Motor drivers – 3x TMC2209 drivers for X, Y1, and Y2 MOSFETs – 2x MOSFETs to control the 2x vacuum pumps Valve drivers – 2x TI DRV120 single-channel relay, solenoid, and valve drivers to control two pneumatic solenoid valves Sensors – 2x CFSensor XGZP6857D I2C pressure sensor modules [...] The post Starfish PnP machine control board combines Raspberry Pi RP2040 MCU with TMC2209 motor drivers appeared first on CNX Software - Embedded Systems News.
