AquaPic modules, board design and firmware

README ====== Board design and firmware for all modules used with the AquaPic Aquarium Controller. Each board should have corresponding firmware that works with that board version. All modules communicate with and are controlled by the master controller/head unit.

All PCB designs and layouts including gerber files are located under the Boards directory. All PCB design is done using KiCAD. Firmware is located in the Firmware directory. All the card's firmware should build without the need of the MPLAB X IDE, just the XC compilers. The Documentation directory contains some useful information…

PH-ORP-Card: common questions

What microcontroller does the PH-ORP-Card use?

The PH-ORP-Card is built around the PIC32MM0064GPM028, from the PIC family.

How big is the PH-ORP-Card PCB?

The PH-ORP-Card measures 80 × 72 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the PH-ORP-Card?

114 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the PH-ORP-Card design files?

From the brandtks/AquaPicModules repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PH-ORP-Card design in my own project?

The repository has no license, so all rights stay with brandtks. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PH-ORP-Card without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
