I contacted Picaxe about upgrading the FET's on the 18m2 high power project board and they said it should be fine but to ask on here in case anyone has already done it and can suggest the right FET's to use. They pointed out they may need heatsinks if going a lot bigger.
Basically the PCB has 4 outputs at 1.5amp and 4 outputs at 1 amp and I just want to upgrade the 1amp ones to 1.5amp ideally.
Has anyone done this and can recommend a suitable FET? It needs the same pin layout as the existing ones.
For background info it's for a project where my customer wants to use 40 x 50mA grain of wheat bulbs spread over two outputs and so the current draw is much higher than with the LEDs I normally use. This links to the other post I've made about using a potentiometer to control flickering of the bulbs.
Thanks.
