Hello,

I am looking for a wearable tracking device for football (soccer) players with the following specifications:

- GPS module with high update rate (preferably 10 Hz or higher)
- IMU sensor (gyroscope, accelerometer, magnetometer, e. G. MPU9250, MPU6050 or similar)
- Programmable microcontroller (e. G. ESP32, STM32 or similar) with SDK access or the ability to upload custom firmware
- Data access via UART, I2C, or SPI
- Charging via USB-C
- Built-in rechargeable battery
- Durable, ready-made enclosure suitable for use in sports (e. G. Wearable on the back or in a sports vest)
- Wi-Fi and Bluetooth modules required
- SIM card support is mandatory (for cellular data transmission)

I will develop my own software, so full technical documentation and communication protocols are required.

I would like to order 1-5 units initially for prototyping and testing.

After successful testing, I am ready to proceed with bulk orders.

Please let me know:
- Do you have such a device available?
- Can you provide a custom version if needed?
- What is the unit price and minimum order quantity?
- What are the lead time and shipping options?

Thank you in advance. I look forward to your reply.

Best regards,
Piotr
