SMA-Q Smartwatch Mini Review and Teardown

I had great hopes for SMA-Q smartwatch, as it features an always on color e-Paper display, a built-in heart rate monitor, and promised 30-day standby battery life, as well as being 30-meter water resistant. But last week, I found out that the latter did not mean waterproof, and instead the watch was rated IP65 that’s only good enough to wash hands and a little rain, but not showering let alone swimming. In the last week, I could play with the watch, and found some serious Bluetooth connectivity issues (with Iocean M6752 smartphone), and I was recommended to upgrade the firmware of SMA-Q watch, and after that my Bluetooth issue have somewhat improve, but everything pretty much went downhill, and the watch is now out of order, and shows no sign of life. So while I was expecting to write a full review, I’ll simply report with experience with the watch […]

GigaDevice GD32 is a Faster, Software and Pin-to-pin STM32 Compatible Cortex M3 MCU

Las month, Olimex discovered a Chinese company called GigaDevice has made an STM32 clone called GD32 and compatible with STM32F103, but with higher core frequency (108MHz). Olimex has now posted an update after receiving a letter from GigaDevice, and trying GD32F103RBT6 MCU on their own STM32F103 boards. The company explained that GD32 was their own implementation, and claimed rights on GD32 trademarks, while Olimex discovered than GD32 was working just fine on their board having passed “all functional tests without any modifications”, and with all the same development tools and software code running fine. GD32F103xx datasheet (PDF / English version) can be downloaded to find a few more details: The GD32F103xx device incorporates the ARM Cortex-M3 32-bit processor core operating at 108 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up to 3 MB on-chip Flash memory and up to 96 KB SRAM memory. […]

GeekBox and Landingship Android Overview and Benchmarks

This week-end I checked out GeekBox TV box, and Landingship baseboard, explained how to connect the two together and install various optional accessories such as an RTC battery and a cooling fan. GeekBox comes pre-loaded with Android 5.1 + Ubuntu dual boot image, and as I’ve already reviewed other Rockchip RK3368 TV boxes, and GeekBox is also a development platform, I’ll simply run several benchmarks on GeekBox, as well as test SATA performance with an SSD connected to Landingship carrier board in Android, before checking out the Linux part a little latter. That’s no quite how you want to place the fan, but I wanted to show the USB to TTL debug board and other wires can be connected with the case closed. This allowed me to easily check whether the fan was spinning during testing, and it never did… According to one forum post, the temperature currently needs to […]

$15 Microchip Curiosity Development Board Supports 8-bit PIC Microcontrollers

I’ve just found out Microchip had introduced Curiosity development board a little while ago, in order to let students and others experiment with their 8-bit PIC DIP MCUs, and including MikroElectronika Mikrobus footprint, an interface for Microchip RN4020 module to add Bluetooth Low Energy, as well as other headers and some extra features like buttons, and a potentiometer. Microchip Curiosity board specifications: MCU – PIC MCU socket for 8, 14, and 20-pin micro-controllers with PIC16F1619 pre-installed. Expansion mikroBUS Click Board footprint Microchip RN4020 Bluetooth Module Footprint USB – USB mini-B connector Misc – Master Clear Reset button, potentiometer, LEDs, mTouch button, push button Power Supply 5V via USB 9V using an external power supply (footprints only) 3.3V to 5V external power supply via TP3 and TP4 pins Dimensions – N/A There are over 160 MikroElektronika Click boars on the market now, but only seven are listed with code samples for […]

Texas Instruments Introduces Entry level Sitara AM3351 Cortex-A8 Processor

Texas Instruments Sitara AM335x processor are designed by industrial applications, and found in develompent board such as BeagleBone Black or BeagleBone Green, and the company has recently launched the new Sitara AM3351 Cortex A8 processor without 3D GPU, no PRU just like AM3352, but they’ve also canned the two CAN interfaces (sorry, I had to) in order to bring the cost lower, while keeping the processor software and pin-to-pin compatible with other AM335x processors available in 13×13 mm package. TI Sitara AM3351 CPU clock will also be limited to 300 MHz to 600 MHz with respectively AM3351BZCE30 and AM3351BZCE60 parts. It will only come with one Gigabit Ethernet port instead of up to two ports of other members of the family that are produced in 15x15mm package, and temperature range is limited to 0 to 90 C. Other features remain the same, and the processors will support TI-RTOS, Linux, Android, […]

GeekBox TV Box Unboxing and Development Kit Assembly Guide

GeekBox is both an Android TV box based on Rockchip RK3368 octa-core processor, and a Linux development kit thanks to the CPU module inside the device, a baseboard and various accessories. The company has sent me a review sample, as well as the accessories currently available. So today, I’ll have a look at the box, and show how to connect everything together. GeekBox TV Box Unboxing I’ve received two carton boxes via DHL, one with GeekBox itself, and the other with some accessories. You could use GeeBox has a TV box, and forget about its development attributes, as the device comes with the usual accessories include a case, an HDMI cable, an infrared remote control, and a 5V/2A power supply. I was really surprised by how small it was compared to other 64-bit ARM TV boxes recently launched on the market, and looks very much like a small router with […]
