"Project Overview: PCB + Processing System Designer Needed for Humanoid Robot (LLM-Ready, Python/C++ Compatible)

I am looking to hire an experienced PCB designer or embedded systems engineer to design a custom control PCB and processing integration module for my humanoid robot prototype.
The system must support actuator control, sensor inputs, audio/video components, and also be capable of running local LLM models (7B or higher) for on-board AI processing.

1. Hardware & PCB Requirements

The board should support:

Actuators & I/O

USB or native interfaces for robotic actuators

PWM, UART, I2C, SPI, GPIO expansion

Support for IMU, proximity sensors, touch sensors, pressure sensors

Cameras & Audio

1–2 camera module interfaces (CSI/USB)

Microphone input

Speaker output

Power System

Stable power regulation for motors + logic

Battery compatibility (12V/24V Li-ion)

Over-current and thermal protection

2. Processing Unit Requirements (LLM Support)

The system must support running local LLM inference, for example:

Ollama models (7B or higher)

Mistral 7B

Falcon 7B

Llama 3 8B

Other optimized quantized on-device models

This means the PCB should either:

Option A: Integrate a powerful SoC module

Examples:

NVIDIA Jetson Orin Nano / Orin NX

Raspberry Pi 5 + external NPU

Orange Pi 5 Plus (16GB RAM)

Khadas VIM4 or VIM3

Rockchip RK3588 boards

Option B: Provide connectors to mount an SoC as the “brain”

Such as:

Raspberry Pi CM4 connector

Jetson module footprint

Dedicated PCIe slot or M.2 slot for AI accelerators

The freelancer should advise the best option given cost, heat, and LLM requirements.

3. Software Compatibility

The system must support:

Programming Languages

Python

C++

Framework Compatibility

TensorRT (optional)

PyTorch / ONNX Runtime

Local LLM inference (Ollama, [login to view URL], or similar)

4. Deliverables

Complete schematic + PCB layout

BOM (Bill of Materials)

Gerber files

3D render

Wiring + interface documentation

Daily work logs and progress updates

5. Ideal Freelancer

Strong experience in robotics & embedded electronics

Has designed PCB boards involving actuators, cameras, IMUs, and audio systems

Knowledge of SoC integrations capable of AI/LLM workloads

Understands power design, heat management, and PCB safety" (client-provided description)
