README.mdOSMP: Open Smart Motor Platform
OSMP (Open Smart Motor Platform) is an open-source hardware and firmware ecosystem specifically optimized for Warehouse Conveyor Systems and automated material handling.
The platform provides a high-precision Hall-sensor interface and integrated memory storage, designed to be embedded within brushless motors used in conveyor rollers, sorters, and AGV/AMR peripheral modules.
Key Features (Current Release)
- Integrated Hall-Sensor Interface: Precision motor commutation and position feedback, essential for smooth low-speed torque control in delicate package handling.
- Onboard Maintenance Storage: Non-volatile memory optimized for storing critical conveyor asset data, including:
- Mechanical Parameters: Roller diameter and gear ratio.
- Operational Logs: Accumulated run-time and hardware versioning.
- Compact Industrial Form Factor: Optimized for 24/7 warehouse operation within space-constrained motor housings.
Future Roadmap (Phase 2 - In Development)
- Extended Motor Parameter Storage: Implementation of advanced data structures to store comprehensive motor-specific characteristics (e.g., PID parameters, current limit...etc.) to enable universal controller auto-tuning.
System Compatibility
The OSMP hardware is fully validated and optimized for use with Bamboo Dynamics TCN-20xZ series controllers. This combination enables high-reliability signal feedback and coordinated motion for synchronized multi-axis conveyor segments.

How to Use
Hardware Customization
The OSMP board is designed to be adaptable to various motor mechanical designs.
- Mechanical Adjustment: Refer to the provided KiCad project files (
MHC-C.kicad_pcb). Modify the PCB outline and sensor placement in the Gerber files to match the specific internal mounting points and dimensions of your motor housing. - Fabrication: Once the layout is adjusted, export the modified Gerber files for PCB production.
Firmware Deployment
To flash the production firmware onto the MCU:
- Equipment & Power Setup:
- Programmer: Use a PICKIT 3 (or later) programmer.
- Power Supply (PSU):
- Connect the VCC of the motor board to a 5V power source.
- Ensure the GND of the board is connected to the PSU GND.
- Software: Install MPLAB IPE (Integrated Programming Environment).
- ICSP Connection: Connect the PICKIT 3 to the ICSP header on the OSMP board according to the following pinout:
| Pin | Description | Board |
|---|---|---|
| 1 | MCLR/VPP | ① |
| 2 | VDD Target | ② |
| 3 | VSS (Ground) | ③ |
| 4 | PGD (ICSPDAT) | ④ |
| 5 | PGC (ICSPCLK) | ⑤ |
| 6 | PGM (LVP) |
- Flashing Procedure:
- Open MPLAB IPE and select the target device (PIC16F18325).
- Load the
MHC-C_production.hexfile. - Click Program to deploy the firmware.

Questions
How big is the MHC C PCB?
It measures 41.3 × 42 mm and has 2 copper layers, 1 mm thick.
What parts does the MHC C use?
44 parts, built around the AZRS3080E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MHC C KiCad files?
From the bamboo-dynamics/OSMP repository on GitHub, at the commit this page was made from: the board is MHC-C.kicad_pcb and its schematic MHC-C.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MHC C design in my own project?
Its repository states no licence, so its author keeps all rights: ask bamboo-dynamics before reusing the design.
