New product (hardware+firmware) based on an existing product

Deliverable: functional prototype with design files (Kicad schematics, Kicad PCB file, Gerber files, BOM, source code, binary)

Scope: inclusion of current sensor to a load control device

Description: We have an old product that uses a relay to connect/disconnect an external load. It receives commands from a bus using a proprietary protocol. We need to add a current sensor to this product.

Architecture: the existing product is based on a PIC12F1840 programmed with Assembly language. We would like to update the microcontroller to STM32F070F6 and the programming language to ANSI C. So the job consists of replacing the MCU and adapting the code to the new platform while adding the ACS712 current sensor and the code needed for it to deliver an accurate measurement.

We already have an enclosure for the product, so board dimensions should not change: 40x50x25 mm.

The code for the proprietary protocol will be supplied in ANSI C.
