$25 “Raspberry Pi 3 mini” board comes with a camera interface, USB & I/Os headers

TPCast-VR, aka “Raspberry Pi 3 mini”, is a compact board based on Broadcom BCM2837 quad-core Cortex-A53 processor, and that should come as part of Element14’s Raspberry Pi customization program, just like the custom Raspberry Pi 3 SBC with eMMC flash designed for laundry gateways that I noticed a few months ago. The board was initially integrated into the power box of the TPCAST Wireless Adaptor for HTC Vive and Oculus Rift virtual reality headsets, but eventually found its way into other applications notably FPV drones, and it’s now sold separately, as we’ll see further below. I found about the board via a tweet from Will Whang who purchased it for under $20 at the beginning of the year, and discovered the connection with the TPCast wireless adapter. TPCast-VR board specifications: SoC – Broadcom BCM2837 quad-core Cortex-A53 processor @ 1.2GHz with Videocore IV GPU System Memory – 1GB RAM Storage – […]

cuplTag battery-powered NFC tag logs temperature and humidity (Crowdfunding)

Temperature and humidity sensors would normally connect to a gateway sending data to the cloud, the coin-cell battery-powered cuplTag NFC tag instead sends data to your smartphone after a tap. CulpTag is controlled by an MSP430 16-bit microcontroller from Texas Instruments which reads and stores sensor data regularly into an EEPROM, and the data can then be read over NFC with the tag returning an URL with the data from the sensor and battery, then display everything on the phone’s web browser (no app needed). cuplTag specifications: MCU – Texas Instruments MSP430FR2155 16-bit microcontroller @ 24 MHz Storage – 2K bytes EEPROM part of NT3H2111 for up to 188 temperature & humidity data points or 376 temperature-only data points Connectivity – Passive NFC, tap-to-read via NXP NT3H2111 NFC tag Sensors – HDC2021 temperature and humidity sensors Measurement interval – 3 minutes to 65535 minutes (Default: 10 minutes) Battery – CR1220 battery […]

Getting started with Bluetrum AB32VG1 RISC-V Bluetooth audio board using RT-Thread

Bluetrum AB32VG1 is a development board based on AB5301A RISC-V microcontroller designed for Bluetooth audio applications as well as general-purpose projects that works with RT-Thread real-time operating system. RT-Thread sent me a board for review, and I’ll write about my experience in a getting started guide for Bluetutm AB32VG1 trying out the RT-Thread Studio IDE with the LED blink and audio samples, as there’s no Bluetooth sample at this time… Bluetrum AV32VG1 Unboxing The board ships with a USB-C cable for power and programming. It offers Arduino UNO headers for expansion, a MicroSD card slot, a USB host port, a 3.5mm audio jack, an IR receiver, and a few buttons. There’s nothing to do on the bottom of the board apart from a QR Core for the WeChat app. There are also several configuration jumpers, but I could not find any documentation about these and did not mess with the […]
