The Sequent Microsystems 8 MOSFETS 8-Layer Stackable HAT for Raspberry Pi is a stackable expansion card for Raspberry Pi. It has four high current channels which can drive 12A/24V loads and four high voltage channels which can drive loads of 4A/240V.
Stackable to 8 layers, the card can provide up to 64 solid-state outputs to each Raspberry Pi. Pluggable connectors make the 8-MOSFETS card easy to use when multiple cards are stacked up. Status LEDs show when MOSFETs are on or off.
The card is compatible with all Raspberry Pi versions from Zero to 5. All stacked cards share the I2C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards. This feature leaves the remaining 24 GPIOs available for the user.
The 8-MOSFETS card needs 5V to operate and can be powered from Raspberry Pi or from it's own pluggable connector. The card draws about 50mA. If power is applied to the card, no other power supply is needed for the Raspberry Pi.
Up to eight 8-MOSFETS cards can be stacked on your Raspberry Pi. Each card is identified by jumpers you install to indicate the level in the stack. Cards can be installed in any order. The three position jumper on the upper right corner of the card selects the stack level.
The latest version of the 8-MOSFET card (V5.0) has several major improvements:
On board processor permits proportional load control using PWM
RS485 port connected to the local processor permits operation as MODBUS RTU slave, replacing the Raspberry Pi with any PLC
Heavy duty, 5mm pluggable connectors can control loads up to 12A
High current channels are galvanically separated from the High Voltage channels
TVS diode protection on high current outputs, diode protection on high voltage
All jumpers replaced with DIP Switches
Software compatible with previous version
