$35 Orange Pi 3 LTS SBC comes with 2GB RAM, 8GB flash, AW859A WiFi 5 and Bluetooth 5.0 module

Orange Pi 3 LTS

Orange Pi 3 LTS is a cost-down, more compact version of Orange Pi 3 SBC launched in 2019 with Allwinner H6 quad-core Cortex-A53 processor, Gigabit Ethernet, four USB 3.0 ports, and mPCIe socket with a PCIe x1 Gen2 lane. AFAICR, the latter never really worked well due to a botched implementation in the SoC. The new slimmed-down Orange Pi 3 LTS is sized like a business card, loses the mostly useless mPCIe socket from the original board, comes with 2GB LPDDR3 RAM (no more 1GB RAM option),  a lower number of USB ports, USB Type-C power input, and an Allwinner AW859A WiFi and Bluetooth module replaces the Ampak AP6256 module from the original board. Orange Pi 3 LTS specifications: SoC – Allwinner H6 quad-core Cortex A53 processor clocked at up to 1.8 GHz with Arm Mali-T720MP2 GPU supporting OpenGL ES 3.1/3.0/2.0/1.1, DirectX 11 System Memory – 2GB LPDDR3 (before 1GB […]

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 […]
