: Inhibit circuit terminals used to electronically reduce armature voltage to zero.

The AC is converted to DC. This stage often includes a large heat sink (like the JYMC-220-I

Sets the maximum output voltage to prevent overspeeding the motor.

The is a specific model of a 2.2-inch TFT LCD display module widely used in the electronics hobbyist and embedded development community. While often unlabeled in generic bulk sales, this module is typically based on the Ilitek ILI9225 driver IC. It is favored for offering a resolution of 176x220 pixels with an SPI interface in a compact form factor, making it ideal for Arduino, STM32, and ESP32 projects.

Because these boards lack isolating transformers, when plugged in.
