In part one, we described how the RCL box works and listed its features and specifications. We also explained how it's built using a Micromite V3 LCD BackPack with a touchscreen and two new boards. Now, without further ado, let's start putting it together. You will of course have to build a Micromite V3 BackPack with its accompanying 3.5-inch LCD touchscreen module to control the whole shebang. If you haven't already done so, refer to the article in the August 2020 issue -the PCB is available from the PE PCB Service, code 07106191. There is one variation from the original design to note: we used female headers (ie, header sockets) on the back of the BackPack PCB to connect to the two other boards used in this project.
