Description

Beacon Mini-TX a mini version of regular Beacon HW v4.9 with IMU

• Has 6D IMU onboard: 3D accelerometer + 3D gyroscope

Comparison to Beacon HW v4.9:

• TX-only beacon – can transmit ultrasonic, but can’t receive it. Beacon HW v4.9 is dual-use: can receive and transmit ultrasonic
• Mini-TX Smaller size and lighter: 47x42x15mm & 25g vs. 55x55x33mm & 62g (or 55x55x64mm with antenna). More on comparision
• Battery – 250mAh vs. 1000mAh in a regular beacon. But Mini-beacon has a new more efficient ultrasonic TX module, thus, battery lifetime in TX mode is even superior to the Beacon HW v4.9
• Tested battery lifetime with 8Hz – 96h. With lower update rate – nearly proportionally longer. Very efficient ultrasonic TX module
• Mini-beacon has only USB (virtual UART) output – no additional pins
• Mini-beacons always have embedded IMU – newer and better, but it has 3D accelerometer and 3D gyroscope, but no magnetometer (which we do not recommend to use indoor anyway, due to magnetic field distortion indoor)
• Embedded antenna – smaller size, but smaller radio coverage ~50m with regular Modem HW v4.9 as compared with ~100m of Beacon HW v4.9 with Modem HW v4.9
• Range in ultrasonic is virtually on par with regular Beacon HW v4.9 – up to 30m with Beacon HW v4.9 as RX beacon. At the same time, for example, a combination of DSP RX beacon + Mini-beacon TX provide a better coverage and a stronger signal, than Beacon HW v4.9 + Beacon HW v4.9
• This HW is for the 915MHz band (US band) only, i.e. 433MHz (EU band) is not supported and not planned. Future HW versions will support another ISM band for the EU – 868MHz. With further limitation of radio coverage, this HW (the 915MHz version) can be used for the 868MHz band already now
