“MaUWB_DW3000 with STM32 AT Command” Review – Using Arduino to test UWB range, precision, indoor positioning

Hello, the device I am going to review is the MaUWB_DW3000 with STM32 AT Command. This is an Ultra-wideband (UWB) module from MakerFabs. The core UWB module on this board is the DW3000 UWB transceiver, and it is also equipped with an ESP32 microcontroller programmable with the Arduino IDE, as well as OLED display. The manufacturer claims that this UWB board resolves multiple anchors and tags mutual conflicts and supports up to 8 anchors and 64 tags. Additionally, the manufacturer has added an STM32 microcontroller to handle UWB multiplexing, allowing users to control the core UWB module by simply sending AT commands from an ESP32 microcontroller to the STM32 microcontroller. More information about this UWB board can be found on the manufacturer’s website. “MaUWB_DW3000 with STM32 AT Command” unboxing MakerFabs sent the package to me from China. Inside the package, there were 4 sets of the MaUWB_DW3000 with STM32 AT […]

DIY ESP32 drone costs about $12 to make

The team at Circuit Digest has designed a low-cost DIY drone controlled by an ESP32 module, based on a custom PCB and off-the-shelf parts that costs around 1000 Rupees to make, or $12 at today’s exchange rate. The DIY ESP32 drone was designed as a low-cost alternative to more expensive DIY drones that typically cost close to $70. The result is a WiFi drone that fits in the palm and controlled over WiFi using a smartphone. Interestingly it does not include any 3D printed parts as the PCB forms the chassis of the device. DIY ESP32 drone key features and components Wireless module – ESP32-WROOM-32 for WiFi control using a smartphone. Storage – MicroSD card slot Sensors – MPU6050 IMU for stability control.
