MFA - Microelectronics For All. MFA is one of the most popular and accessible microelectronics teaching packages. This MFA Decisions Module board is used to establish the ideas of inputs and outputs, high and low 'logic' levels, and how decisions are based on a set of conditions. The board carries four input devices: a slide switch, a push switch, a thermistor and a light sensor plus a socket for an external sensor. Outputs are a buzzer, an on/off relay and a bulb. The central section of the board provides a NOT gate (inverter), an AND gate and an OR gate. All inputs and outputs are via 2mm sockets, with on-board LEDs to display the state of signals.
