Wiki Link : ESP32 UWB Pro with Display

Ultra-wideband (UWB) is a short-range, wireless communication protocol that operates through radio waves, enables secure reliable ranging and precision sensing, creating a new dimension of spatial context for wireless devices.

This new ESP32 UWB pro with display is the updated version of ESP32 UWB Pro, with the following new spec:

• On-board OLED, 1.3” 128*64, so the distance results can be directly displayed
• Lipo battery charger& connector, so this module can work separately with batteries
• Update UWB position, so the module can be directly installed into a case

Example

Compiler Options

If you have any questions，such as how to install the development board, how to download the code, how to install the library. Please refer to :Makerfabs_FAQ

• Install board : ESP32 .
• Rename mf_DW1000.zip to DW1000.zip and install it.
• Install library : Adafruit_SSD1306
• Upload code, select board "ESP32 DEV"

**This library was modified from the DW1000 library to work with the Makerfabs hardware. **

Please download the latest version from our Github.

Example List

uwb_tag

For ESP32 UWB and ESP32 UWB Pro

Distance to the receiving end of the test. You need an anchor point to receive data.

uwb_tag_display

For ESP32 UWB Pro with display

Distance to the receiving end of the test. You need an anchor point to receive data.

anchor

For ESP32 UWB and ESP32 UWB Pro

Distance test anchor point.

anchor_display

For ESP32 UWB Pro with display

Distance test anchor point.

Indoor positioning

For ESP32 UWB and ESP32 UWB Pro

Three UWB modules were used for indoor plane positioning. Data is transmitted through UDP protocol and graphically displayed in Python.

The law of cosines is used to calculate tag coordinates.

def tag_pos(a, b, c):
    # p = (a + b + c) / 2.0
    # s = cmath.sqrt(p * (p - a) * (p - b) * (p - c))
    # y = 2.0 * s / c
    # x = cmath.sqrt(b * b - y * y)
    cos_a = (b * b + c*c - a * a) / (2 * b * c)
    x = b * cos_a
    y = b * cmath.sqrt(1 - cos_a * cos_a)

    return round(x.real, 1), round(y.real, 1)
