Project Summary

Digital Dividend was contracted by an engineering company to develop schematics, firmware, and PCBs for custom IoT energy units, including microcontroller programming and hardware testing. The vendor delivered prototype and final PCB designs, implemented firmware and GSM connectivity to transmit data to the cloud, and managed the work via biweekly sprints. The client praised timely delivery, effective time management, and high-quality outputs.

Key Challenges

Develop schematics and PCB for customized IoT units
Develop firmware for IoT units based on Arduino platform
Conduct hardware and PCB testing with firmware

Project Deliverables

AC voltage and current measurement circuit simulations
Integration with STPM IC
Microcontroller firmware for USART/SPI data retrieval
Data packet encoding and checksum implementation
Single-channel prototype PCB design and assembly
Hardware testing per provided test cases
GSM module programming for AWS data transmission
Multi-channel PCB design and final hardware and software testing

Project Solution

The vendor simulated AC voltage and current measurement circuits and integrated them with the STPM IC, developed microcontroller firmware to retrieve parameters over USART/SPI, encoded data into packets with checksums, and designed, manufactured, and tested prototype and final multi-channel PCBs. They also implemented GSM-module programming to transmit telemetry to the AWS cloud and executed hardware tests according to client test cases.

Project Outcome

Successful PCBs meeting the client's requirements and validated through testing
On-time delivery with regular biweekly meetings and Scrum-managed sprints
High-quality design and project management praised by the client
