Battery management PCB correction for portable UV light
Excellent work from Muhammad and his team. We weren't able to do what we needed to, but that was a result of technical barriers and had nothing to do with their performance. We particularly like their meticulous documentation.

Steps for completing your project
After purchasing the project, send requirements so Muhammad Hammad can start the project.
Delivery time starts when Muhammad Hammad receives requirements from you.
Muhammad Hammad works on your project following the steps below.
Revisions may occur after the delivery date.
Understanding Requirements
Discuss target MCU, communication protocols (UART, SPI, I2C, CAN, BLE, etc.), and project functionality.
Code Architecture & Setup
I’ll structure your firmware for scalability and modularity (FreeRTOS or bare-metal C/C++).
