Netherlands based NickStick BV has developed a motor driver board powered by an ESP32 dual-core WiFI and Bluetooth module and capable of controlling brushless DC motors.
The SwarmDrive board targets users who want to start experimenting with motor control, and learn about commutation strategies, PID for balance plateau or balance robots, cartesian gantries and spatial navigation, drive by wire and wireless, swarm intelligence experiments, etc.
- Wireless module – Espressif Systems ESP32-WROOM-32D module with ESP32 dual-core processor @ 240 MHz, 4 Mbit flash
- 2.4 GHz 802.11 b/g/n WiFi up to 150 Mbps
- Bluetooth v 4.2 BR/EDR and BLE
- Motor Control
- L6234 triple half-bridge motor driver, 5 A peak current
- 3-pin terminal block for motor output
- 3x enable pins are broken out to a bridging connector
- Programming and debugging – Micro USB serial port via USB to UART bridge,
- Misc – Boot and reset push-buttons
- Power Supply
- Supply Voltage – 7-13 V via screw terminal or pin headers
- Power output pins – 5 V, 3.3 V, and GND
- Dimensions – TBD
SwarmDrive ESP32 motor driver board has recently launched on Crowd Supply with a $2,500 funding target. The board is offered for $75, and a bit less per unit in bundles of up to 5 boards. Shipping is free to the US and adds $10 to $17 to the rest of world. Backers should expect their boards to ship at the beginning of February 2021.
