ESP32 UWB board features DW1000 module for accurate indoor positioning

ESP32 UWB board

FiRa “Fine Ranging” UWB technology was introduced a few years ago and is now found in devkits and Apple U1 chip. Makerfabs ESP32 UWB board provides another option with Espressif ESP32-WROVER-32 or ESP32-WROOM-32 WiFi & Bluetooth module combined with a Decawave DW1000 module for precision tracking. Makerfabs explains the board acts like a continuously scanning radar that locks onto another device (called Anchor, since it’s usually in a fixed location) and communicates with it to determine the distance between objects by calculating the time of flight (ToF) between devices, or in other words, the roundtrip time of challenge/response packets. ESP32 UWB board specifications: Wireless modules: WiFi & Bluetooth LE – ESP32-WROVER-32 or ESP32-WROOM-32 module with ESP32 dual-core processor @ 240 MHz UWB – B&T BU01 module based on Decawave DW1000 chip; IEEE802.15.4-2011 UWB compliant wireless transceiver module with a precision of 10cm indoors, a data rate of up to 6.8 […]

Unsurv offline – An ESP32 GNSS receiver board with NFC, accelerometer (Crowdfunding)

unsurv offline

Unsurv offline is a compact and lightweight board with ESP32 WiSoC, a GNSS receiver, an accelerometer, and NFC capabilities to help developers/users collect and analyze location data in a privacy-friendly way. Unsurv Technologies initially developed the board to better understand offline video surveillance with OpenStreetMap (OSM) data. It does so by using a database of camera locations from the OSM on the SD card, “counts” surveillance cameras as you walk past them, and you can then transmit data via NFC and visualize it on your smartphone. The accelerometer is used to wake up the board from deep sleep upon detection of motion. The company has now made the board open-source and other applications are also possible. Unsurv offline specifications: Wireless modules TTGO T-micro32 WiFi 4 and Bluetooth 4.2 module based on ESP32-PICO-D4 SiP with dual-core ESP32 processor, 4MB FLASH, ceramic antenna U-blox CAM-M8C (aka u-blox M8) module with concurrent reception […]

Develop USB Host and Device applications with ESP32-S3-USB-OTG board

ESP32-S3-USB-OTG board

ESP32-S series chips like ESP32-S2 and ESP32-S3 come with a USB OTG interface, and Espressif unveiled the ESP32-S3-USB-OTG board last September in a post entitled “ESP-USB: Espressif’s Wireless Communication Solution“, where they mostly focused on USB code samples with documentation in Chinese only and provided few details about the board itself. But I browsed the company’s official Aliexpress store earlier this week, and I noticed ESP32-S3-USB-OTG board was up for sale for $35 plus shipping, with additional information now available, so let’s have a closer look. ESP32-S3-USB-OTG board specifications: Wireless module – ESP32-S3-MINI-1-N8 module with ESP32-S3 dual-core Xtensa LX7 processor with WiFi 4 and Bluetooth 5.0 connectivity, 8MB QSPI flash Storage – MicroSD card socket Display – 1.3-inch color LCD USB 1x Full-speed USB host port 1x Full-speed USB slave port 1x Micro USB port for debugging (UART console) Expansion – 14 pads with 6x GPIO, JTAG, 3.3V and GND […]
