Aceeca’s Meazura is especially interesting because of its MZIO slot that allows hardware to be added without significant effort. Aceeca has created a lowcost developer module to simplify development…and vivomobile sent us a few free samples.
Basically, your module consists of three separate PCB’s as shown below. The ‘main’ PCB contains the soldering isles where you connect to the bus. The side PCB usually mates with connectors…but these aren’t present on the cheaper(I prefer this one to the one with endcap) version. Instead, you can route wires through the holes. The IR PCB is completely useless most of the time…it just contains the IR transmitter:
Essentially, you solder wires to the main PCB and route them outta the holes to your circuit. However, there are a few FAQ’s which are answered below:
Is the IR board always connected to the Meazura
Yes. The signal path is shown by the arrows in the figure above…you can easily trace them on your board. As long as the circuit you build doesn’t interfere with the Meazura’s UART2, the IR system will work like it would with any other module.
Is there any kind of protection for the Meazura on the board
No. 5V or a short circuit…and the Meazura is done for…
Is the Meazura waterproof with the board installed
Nope! Treat a Meazura with a dev module inside like a Palm IIIc or a similar, very sensitive handheld…
