Not sure if sharing this info via github repos is t he way to go, but let's give it a try. 3 | 4 | Whenever possible, attribution to the board's creator will be given. Many of these tiny boards I buy are some kind cheap clone or nameless knockoff. These will be "by unknown". If anyone knows the origin of a baord covered here, please create an issue with the attribution or anecdotes. 5 | -------------------------------------------------------------------------------- /D4184/README.md: -------------------------------------------------------------------------------- 1 | This board is sold via Amazon as a "Trigger Switch Drive Board 0-20KHz PWM" and various other titles. It is essentially a N-MOS breakout board. Literally functions as an n-channel mosfet with terminal lugs. And a spare terminal. 2 | 3 | Inputs and Outputs: 4 | - Vin(-) and J1(-) of the input are electrically common and are the "Source" of the mosfet. 5 | - TRIG / PWM J1 input goes to the "Gate" of the mosfet. There is a resistor between the input and the shared fet's Gate inputs. 6 | - Vout(-) is the "Drain" output of the mosfet board. 7 | - Note that the Vin+ and Vout+ exist solely as a terminal connection; these "+" connections are not used anywhere else on the board. This should be made far more obvious on the silkscreen. 8 | 9 | A few listings of the board. *if you want to add more, ask to be a contributor and you maintain it* 10 | * [Amazon ASIN:B07XJSRY6B 10 pcs](https://www.amazon.com/dp/B07XJSRY6B) 11 | * [Amazon ASIN:B077TX1J44 1 pc](https://www.amazon.com/dp/B077TX1J44) $6.99, *great pics* 12 | * [Amazon ASIN:B085VD5YZJ 8 pcs](https://www.amazon.com/dp/B085VD5YZJ) $12.99 13 | 14 | Interestingly, the boards all have slightly different silk screen and different "part numbers" on the bottom in the center.
