MOSFETs are the go-to technology for controlling large loads from a microcontroller. As technology has advanced, and processor voltages have moved to 3.3v and below, MOSFETs have become available which will turn on with ever lower gate voltages. Unfortunately for many hobbyists, these modern low-voltage MOSFETs have often remained out of reach - while 4.5v logic level MOSFETs were made in through-hole packages, the lower voltage ones are available almost exclusively in surface mount packages.
One might expect breakout boards to be common - but while eBay and Amazon are full of 4-channel MOSFET driver boards... unfortunately these almost exclusively use old "standard" voltage MOSFETs or 4.5v logic level MOSFETs. It's never been clear to me why this was the case - but that's why I decided to offer these boards. This is an updated version of this board based on the AOD-476, which has since been discontinued - this board uses the IRF3708 instead.
This is a 4-channel MOSFET breakout board, made with the IRFR3708 logic level MOSFET, spec'ed for use with voltages as low as 2.8V on the gate, making them well suited for control with modern 3.3v electronics. These MOSFETs support switching loads up to 30V and are rated for continuous current of 20A @ 100C Tc (case temperature), 25A @ 25C. See documentation link for full specification.
Sold as an ASSEMBLED BOARD - with or without screw terminals. The bare board can be purchased here
