The Bill-of-Material (BOM) for each board in CTR2-Mini can be found below. Links are provided for Mouser.com. You can use the part #s to find these parts at other part suppliers. Click the Download button to download the file.
I have created automated BOMs on Mouser.com to help you order the parts needed to build a CTR2-Mini or CTR2-Mini+. You can also order completely assembled and tested Mini’s from the order page.
You can build the Mini or Mini+ on a perf-board if you really want to. The BOMs don’t provide part #s for the through-hole versions of the SMT parts if you choose to go this route. I can supply PCBs for all the required boards with SMT parts pre-installed at a very reasonable cost (and way cheaper than buying the through-hole parts). I can also supply an enclosure kits if you want to package your Mini as shown on this site. The Mini enclosure includes the custom acrylic stand, machined Hammond enclosures for the encoder/speaker and and one Radio I/O module, mounting hardware, and a knob for the encoder. The Mini+ enclosure is a CNC machined PacTec KEU-5 enclosure ready to install your PCBs into. Of course you can build your own enclosures instead.

Mouser: CTR2-Mini+ Controller v1: This BOM includes the through-hole parts required to build the front panel and base boards for the Mini+ radio controller. It also includes the Wio Terminal and the PacTec KEU-5 enclosure. You should remove these from your order if you already have a Wio Terminal or are going to order the CNC machined PacTec KEU-5 enclosure from me.
Mouser: CTR2-Mini Controller v1: This BOM includes the required through-hole parts to build the Main board, GPIO Interface board, and Encoder/Speaker board. It also includes the Wio Terminal in case you haven’t already purchased a Wio Terminal for this project. I found the small speaker on Mouser and added it to the BOM so you don’t need to order it separately from Adafruit.
Mouser: CTR2-Mini Radio I/O_v1: This BOM includes the through-hole parts required to build one Radio I/O module. Order the PCB and machined enclosure here.
Mouser: CTR2-Mini_Encoder+Radio_Enclosures_v1: If you don’t order the enclosure kit from me, use this BOM to order two Hammond 1551HBK enclosures. One is for the Encoder and one is for the Radio I/O board. You will need to drill and cut the required openings.
Mouser: CTR2-Mini_Optional_Relays_v1: This BOM includes the flyback diodes and reed relays to convert your Mini to use dry-contacts on the Key and PTT circuits. This is only required if your rig cannot be keyed by a solid-state device (i.e. keying voltage is >+50 volts DC or negative).
Kicad produces a very nice interactive BOM that is very handy when assembling the PCB. Just open the desired file in a browser and point to each component to highlight it on the board. All four boards are zipped into the file below.
