Firmware Development Jobs

I’m looking for a freelancer who can help me perform SW updates to the Automotive Audio Amplifier. The parts are not in the vehicle and are located in El Paso. Here’s what I need from you: • Identify the correct update package for the hardware revision and regional SKU. • Prepare the setup for flashing using the directions from the Supervisor. • Execute the update, capturing logs so we can verify a complete, error-free install. • Follow required protocol to ensure traceability and ensure things are working properly. If you’ve worked with OEM infotainment systems, custom ROMs, or related tools such as ADB, QFIL, or OEM flashing utilities, that’s a plus. Required short term contract of 2-3 weeks (potentially future contracts depending on p...

I am seeking a freelancer to write well-commented template that turns an Adafruit Feather ESP-32 single board computer into a tiny WebSocket server. Later I will expand that template into a mini OCPP (Open Charge Point Protocol) server and add more functionality. The target board is the Adafuit ESP32-S2 Reverse TFT with a ST7789 display. The deliverable is a tiny compile ready package on the complexity of the example at * Boots up and serves out a small HTTP web page for testing. * Each browser client can send a number to the tiny server via websockets. * The tiny server stores each number persistently. * The tiny web server flashes each received number on the built in TFT display. * The tiny web server returns the total number of numbers logged back to the browser clients, whi...

I need a skilled PCB designer to convert my existing through-hole PCB, designed in Fritzing, into an SMD PCB for production using KiCad. The design works great, but I need it to be SMD. Requirements: - Convert the following components from through-hole to SMD: - ICs (including ESP32, A7670G modules, and charge controller) - Use of standard footprints for all SMD components. Ideal Skills and Experience: - Proficiency in KiCad - Experience with SMD PCB design and layout - Familiarity with the specified components (ESP32, A7670G, charge controllers) - Attention to detail and accuracy in design Please provide samples of previous SMD PCB designs.

My BMZ Power2Go Work portable power station—just 14 months in service—shut down abruptly while delivering a steady 1 600 W load (it is rated for 2 500 W continuous, 3 600 W peak). Since that moment it refuses to charge or power on; every status LED remains dark. I need a battery technician who can carry out a full diagnostic and bring the unit back to life. That means opening the enclosure, verifying cell health, checking the BMS, charger circuitry, DC-AC inverter stage, and any internal fuses or relays. Once the fault is identified I want the defective components replaced or rebuilt so the pack can once again charge fully and supply its original output ratings without thermal or voltage irregularities. Deliverables: • Detailed test report outlining root cause, measureme...

iPhone Battery Management System inside-out and can work across software, hardware, and firmware layers to alter the way battery health data is reported. The goal is to change the internal metrics that feed the Health section in iOS so the device shows revised capacity, cycle count, and related statistics without triggering errors or safety lockouts. Can you make a Custom device that can be use on a factory level,hat helpful to change battery health and cycle by just connecting the battery BMS only. Scope • Reverse-engineer or otherwise access the BMS firmware and its data pathways. • Modify the algorithms or calibration tables that calculate battery health. • Validate the change on real hardware so the phone operates normally under charge, discharge, and idle state...

Hello PCBWay, I need you to design and supply a fully assembled, programmable PCB for a battery-powered motion recorder. I do not have a schematic and cannot solder components myself. Please check whether an existing design could be adapted to reduce the cost. **Shape and size** - Rectangular PCB with rounded corners. - Standard credit-card dimensions: 85.60 × 53.98 mm. - Keep the PCB and components as thin as practical. - A separate flat LiPo battery will sit behind the PCB. Please keep the battery area clear of tall components. **Hardware** - A low-cost, low-power microcontroller that I can program myself. - An onboard 3-axis accelerometer and 3-axis gyroscope. - Two assembled push buttons: 1. Power on/off. 2. Start recording; press the same button again to stop and save. - One pro...

I need a production-ready PCB for an industrial ranging device that will be integrated into larger automation machinery on our factory floor. The board has to combine three core capabilities: robust signal processing of the sensor data, reliable high-power outputs to drive downstream actuators, and on-board wireless communication for status reporting and firmware updates. The footprint must stay within 80 mm × 60 mm, operate from a 24 V DC rail, and meet industrial EMC/EMI standards (EN 61000 family). A multilayer stack-up with controlled impedance traces for the RF section is expected, along with generous creepage/clearance on all high-current paths. Deliverables • Schematic (Altium or KiCad) • Fully routed Gerber/ODB++ files ready for fabrication • Annotated ...

I need a complete electrical design for a true-online 600 W UPS that will operate in a home environment. The scope covers everything from the high-level architecture down to production-ready documentation, so that I can have the unit prototyped and assembled without further engineering work. What I expect you to produce includes: • Full schematic with clearly annotated component values • Bill of materials using readily available parts • PCB layout files (Gerber or equivalent) and 3-D board view • Control logic or firmware source (if a microcontroller or DSP is used) • Mechanical outline showing heat-sink placement, transformer or inductor dimensions, and suggested enclosure size • Brief test plan describing how to verify continuous 600 W output, transfer time...
