Further Information

I would like to connect leds, a motor, and a 7- segment display to an Arduino or Picaxe microcomputer. Would this be suitable? If not, please could you recommend a microcomputer. Also, how would I program this?
Thank you for your help,
Asked by: Bradley Michael Collins

Hi Bradley, Depending on how many inputs and outputs you want will depend on what kit you need. You may find it easier to use a PICAXE kit such as the PICAXE-18 Project Board, 3708-picaxe-18-project-board or the PICAXE-20 Project Board, 3718-picaxe-20-project-board Both of which can output to 8 different items, and can drive motors. We also have a guide for getting started with PICAXE which might be useful, use-picaxe

Hello, I understand that the dimensions given are for the pcb without components attached. What is the height (thickness) of the populated pcb, please?
Asked by: Tom
Hi Tom, The product is already populated with the surface mount components and the height stated of 0.8mm is correct, the tallest part of the board is where the micro-USB connector is located and I measured this to be around 0.7mm. So a little bit of tolerance but the 0.8mm is likely to be accurate.
