The object's surface area should be greater than or equal to the cross-sectional area of the electromagnet (20mm x 15mm)
You have 13 GPIO pins on the IC to control your project which you can use to control various actuators and LEDs but you will need an additional relay or driver to control motors as max output current is 25mA
Supply Voltage Range: 2V-6V
and house a field generator
It is a toned down version of ST link V2 In line programmer/ debugger for STM8 and STM32 microcontrollers
LR7843 MOSFET Control Module for Relay Replacement Piezoelectric Sensor The object's surface area shouldThe LR7843 MOSFET Control Module is a high power switching module designed to replace traditional relays, providing faster response, longer lifespan, and higher efficiency. It uses the LR7843 MOSFET, known for its low Rds(on) resistance and high current handling capacity. This module is ideal for motor control, LED dimming, battery charging, and DC power switching applications. Features of LR7843 MOSFET Control Module: Solid state relay replacement
