The Pressure Paddle V2.0 simplifies the original 2019 design by using MOSFETs’ unique properties for reliable, minimalistic switching. When pressure sensors detect a press, they reduce resistance, activating the MOSFET and lowering voltage until it stabilizes at the MOSFET’s threshold. This ensures consistent “key down” signals for the transceiver. Compatible with 3-5V logic systems, the circuit operates independently of pull-up resistor size. The PCB is lightweight, easy to assemble, and can be packaged in heat shrink or mounted. This version maintains durability with fewer components and flexible packaging options.
