Waxberry Pi3 Rockchip RK3188 Development Board Includes a SATA Port

Development boards based on Rockchip RK3188 are a rarity, and until today, I only knew about Radxa Rock boards. Waxberry, a Chinese based company, already made some development boards such as Waxberry Pi2 based on Rockchip RK3066, and recently they’ve launched Waxberry Pi3 development board powered by Rockchip RK3188 processor, with 1 GB RAM, 8 GB flash, a SATA port, expansion headers and more. Waxberry Pi3 (aka WB-RK3188) specifications: SoC – Rockchip RK3188 ARM Cortex-A9 quad core @ 1.6Ghz + Mali-400 MP4 GPU System Memory – 1GB RAM Storage – 8GB NAND Flash (SK Hynix H27UCG8TETR) + micro-SD slot + SATA port Video Output – HDMI, LVDS connector, and AV output (TBC) Connectivity – 10/100M Ethernet port, 802.11b/g/n WiFi Audio I/O – HDMI, AV?, mic IN Camera – 24-pin CSI connector USB – 2x USB 2.0 host ports, 1x micro USB OTG Misc – IR sensor, RTC with battery slot […]

$25 TinyScreen is an OLED Display for TinyDuino Arduino Compatible Board (Crowdfunding)

Back in 2012, Tiny Circuits launched a Kickstarter campaign for TinyDuino, an Arduino compatible board that’s… tiny, based on Atmel Atmega328P, and supports tiny stackable shields in a similar fashion to Microduino (launched in 2013). The campaign was successful, and the company is now back on Kickstarter with TinyScreen, an OLED display that can be stacked on top of TinyDuino to create a smartwatch, a minuscule gamepad, smart glasses, and more. TinyScreen technical specifications: 96×64 OLED display, 16-bit color depth 0.96″ (24.4mm) viewable area Software controllable backlight (OLED brightness) Power down mode Four push buttons along the sides (connected to IO pins) SPI interface for display Power Supply – 3.0V to 5.5V operation (higher voltages supported with TinyShield power regulator) Power Consumption – 20 – 45mA max supply current (depending on brightness) Dimensions – 25.8mm x 25.0mm Programming of TinyDuino can be done through a web interface for Arduino called […]

KDDI Unveils Tiny BLE/Zigbee Development Board Running Mozilla Firefox OS

KDDI has recently announced Open Web Board, an HDMI TV stick powered by Rockchip RK3066, and running Firefox OS, just like the recently announced MatchStick. The board is however aimed at embedded and web developers who want to create apps for Firefox OS, and interface with external devices over Bluetooth Low Energy or Zigbee (optional module) communication, optionally using Gluin, a web based graphical “application development tool that enables simple linking programming between electronic devices”. Open Web Board specifications: SoC – Rockchip RK3066 dual core Cortex A9 processor @ 1.6 Ghz with Mali-400 MP4 GPU System Memory – 1 GB RAM Storage – 8 GB flash Video Output – HDMI USB – 1x USB 2.0 host port, 1x micro USB for power Connectivity – 802.11 b/g/n Wi-Fi (AP6210 module), Bluetooth 2.1 (HFP/A2DP/AVRCP)/4.0 GATT. and optional Zigbee via external module Dimensions – Small This dongle runs Firefox OS 1.4. KDDI showcased […]

Current Performance and Stability Issues on AllWinner A80 OptimusBoard Development Board

Sine A80 OptimusBoard is the first ARM hardware that supports both USB 3.0 and Gigabit that I’ve ever owned, so I though it might be interesting to see what performance I could get with a USB 3.0 hard drive through the USB 3.0 OTG port of the board. For testing purpose, I bought a USB 3.0 OTG adapter on Ebay, but I did not look closely enough as it turned out to be only a USB 3.0 OTG to USB 2.0 female adapter capable of USB 2.0 speeds… Kind of useless item since you can plug a standard USB 2.0 OTG adapter into a USB 3.0 OTG receptacle. But I tried my hard drive anyway, and quickly realized write performance was very poor at 3 MB/s on the NTFS partition, whereas most other devices can handle at least15 MB/s, and usually over 25 MB/s. So I contacted Allwinner with this […]

HydraBus is an Open Source Hardware STM32 Devkit with Support for NFC via HydraNFC Shield

Recently, I wrote about the public availability of a MicroPython board based on STMicro STM32F4 Cortex M4 support that can easily be programmed with Python. It turns out there’s another STM32 board called HydraBus, also supporting Micro Python firmware, or another embedded firmware based on ChibiOS, together with an optional HydraNFC shield capable of sniffing, reading/writing or emulating any 13.56MHz NFC tags. HydraBus Specifications: MCU – STMicro TM32F405RG micro-controller @ 168 MHz with 1MB flash, 192KB SRAM, and an FPU. External Storage – Micro SD card slot up to 48MHz (~24MB/s) Expansion Headers – 4 headers with access to 44 I/Os (some already used by micro SD and USB 1 & 2). USB – 2x micro USB connector including 1x OTG port, and 1x device/host port, both with ESD protection. Misc – Reset and user button, user LED, Power – 5V via micro USB port. Dimensions – 60mm x […]

Firefly-RK3288 Development Board is Now Available for $189

Three days ago, a T-chip representative informed me privately that Firefly development board (Rockchip RK3288) would not be available on foreign websites, and that it was unclear when the board would be selling in China. So either I’ve been lied to, or there’s poor internal communication within the company, as they’ve now listed Firefly-RK3288 board on Taobao for 800 CNY (~$130), and it’s also available on GeekBuying for $159 including shipping, possibly by somebody unrelated to T-chip, especially there are only 3 units for sale. Let’s go the specifications that have slightly changed since the original announcement: SoC – Rockchip 3288 quad core ARM Cortex A12 / A17 up to 1.8 GHz with Mali-T764 GPU supporting OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1 System Memory – 2G DDR3 Storage – 16 GB eMMC flash + micro SD slot Video I/O HDMI 2.0 up to 3840×2160@60p VGA out (D-SUB connector) Dual MIPI, Dual LVDS and and EDP […]

Pyboard MicroPython ARM Cortex M4 Board is Now Available for $45

MicroPython is both a lightweight implementation of Python 3.4 programming language, and a board, aka pyBoard, based on STMicro STM32F4 ARM Cortex M4 micro-controller running Micro Python. The project had a successful Kickstarter campaign in 2013, and they’ve completed shipment of the perks to their backers last June. The company has now launched its own store, so let’s see the progress of the project. The board has been re-designed since Kickstarter campaign, but the specifications remains the similar, but with some extra I/Os exposed: MCU – STMicro STM32F405RG micro-controller @ 168 MHz with 1MB flash, 192KB RAM, and an FPU. External Storage – Micro SD card slot, supporting standard and high capacity SD cards Expansion Headers: 24x GPIO on left and right edges and 5x GPIO on bottom row, plus LED and switch GPIO available on bottom row 3x 12-bit analog to digital converters, available on 16 pins, 4 with […]
