Vigekwear is a Modularized, Open source, Wearable BLE Development Kit (Crowdfunding)

[Update: Atomwear has been renamed to Vigekwear due to (Intel’s) copyrights infringement]. Giayee is a company mainly manufacturing Android tablets, thin clients, and mini PCs, but their latest product, called Atomwear, is a Bluetooth Low Energy (BLE) development kit based on Nordic nRF51822 chipset that comes with various modules such as battery charger, accelerometer, gyroscope, OLED display, heart rate monitor, etc… which connect together via 24-pin connector on a standard rigid baseboard or a flexible printed circuit (FPC). All modules are connected via the same 24-pin connector with power, I2C, SPI, UART, ADC, and GPIOs signals. The baseboard and FPC both contain 6 such connectors connected in parallel for up to 6 modules, and two baseboard can be connected together via a bridge circuit to accept more modules. The minimum configuration is with a BLE MCU module, and a power module. The different boards and modules are listed as follows: […]

Hardkernel Unveils $30 Raspberry Pi Compatible Module with RTC, ADC, and LiPo Battery Support

Hardkernel is better know for its ODROID boards powered by Samsung Exynos SoC. So I was surprised to discover ODROID-W, “a miniature computing module which is fully compatible with all software available for the Raspberry-Pi”.  Software compatible, really? Yes, because they used the same Broadcom BCM2835 SoC found in the Raspberry Pi, packaged it in a smaller form factor, while keeping HDMI, USB, and CSI interface, and expansion headers, and all that for $30, plus just $9 for shipping. Let’s go through ODROID-W specifications first: SoC – Broadcom BCM2835 ARM1176JZ-F processor @ 700 Mhz with VideoCore IV GPU System Memory – 512MB LPDDR2 (Samsung K4P4G324EB PoP) Storage – microSD slot + eMMC socket (bottom of the board) Video Output – micro HDMI (with NXP IP4791CZ12 protection IC) USB – micro USB connector, and USB host (not soldered) Expansion Headers: R-Pi compatible 26-pin expansion header (through holes) R-Pi compatible 15-pin CSI […]
