Sequent Microsystems 8-Layer Stackable HAT

Sequent Microsystems 8-Layer Stackable HAT is an expansion for Raspberry Pi with eight solid-state drivers. The Sequent Microsystems hat features four channels for high current (8A/24V) and four for high voltage (2A/240V), allowing stacking up to eight layers for a total of 64 outputs. Pluggable connectors simplify use when stacking multiple cards, and status LEDs indicate MOSFET status. Compatible with all Raspberry Pi versions (Zero to 5), it shares the I2C bus, utilizing only two GPIO pins. Powered by 5V, it draws 10mA, eliminating the need for an additional power supply for the Raspberry Pi when connected. Stacking up to eight cards is possible, with jumpers identifying each card’s level. Jumper placement in the upper right corner determines the stack level.
