Energympro EP-SH09 Bluetooth LE Fitness Tracker Features AMS AS7000 Biosensor

I wrote about AMS AS7000 biosensor designed for heart rate monitors last fall, and one of my regular reader noticed the sensor, made his company evaluate it, and since the results were pretty good, designed a product with it. And here I am with a sample of Energympro EP-SH09 fitness tracker with an OLED display, HRM based on AS7000 sensor, and IP67 ingress protection rating. Some of Energympro EP-SH09 technical specifications: MCU – Texas Instruments CC2640 ARM Cortex-M3 48 MHz Display – 0.86″ OLED display, 96×32 resolution Connectivity – Bluetooth 4.0 LE Input – Touch area at the bottom of the display Sensors – AMS AS7000 biosensor for HRM, motion sensors Battery – 45 mAh LiPo battery which looks good for 4 to 5 days.

Xiaomi Mi Band 2 Fitness Tracker Adds an OLED Display, Promises 20-day Battery Life

I’m not a big fan of fitness trackers without display that require you to monitor your daily progress on your smartphone, and that’s probably why when Xiaomi released their first fitness band I was not quite as interested, but now the Chinese company has released Mi Band 2 with an OLED display, an heart rate monitor,  IP67 ingress protection rating, and a 20-day of battery life for just 149 RMB ($23). Mi Band 2 key features: Fitness, heart rate and sleep tracker OLED display, view time, step count, heart rate 20-day battery, IP67 water resistant ADI accelerometer and optical heart rate sensor Anodized 0.05mm ultra-thin button Upgraded pedometer algorithm Hypoallergenic silicone band 2nd gen Bluetooth 4.0 for faster, stable connections It’s still good to be able to gather your fitness data over time, and you can do so with Mi Fit app for Android or iOS. The downside with an […]

F68 Smart Watch Review

After No.1 D3 and SMA-Q smartwatches, Makibes F68, or just F68, is my third attempt at reviewing a smartwatch, and on paper it matches all of my main requirements namely always-on display, fitness tracking with heart rate monitor, one week of battery life, and IP67 ingress protection rating to have some waterproofness. I’ve already taken pictures of the device, so today I’ll go through the user interface on the watch, and Android app, and report my experience after using the watch for over 10 days. The watch has an e-Paper display with decent viewing angles, and very good readability during the day, however at night, you’ll need to find the light switch or use a torchlight, as the watch does not have backlight at all, and it’s unreadable. There’s actually no buttons at all and everything is controlled via the touchscreen, and/or the app available for Android or iOS. The […]

Samsung S3FBP5A Bio-Processor Targets Fitness Tracking Wearables

We now have many wearables capable of monitoring your activities, be it smartwatches or fitness tracker, and usually they are comprised of several small sensor chips, a low power micro-controller, a Bluetooth radio, and possibly some other ICs . Samsung has been designing and just launched a bio-processor to regroup most of those features into a single chip which should only require a fourth of the area required by current multi-chip solutions. While the press release did not mention the part number, the included picture – shown above – sort of gave a clue, and Samsung S3FBP5A bio-processor has the following specifications: MCU – ARM Cortex-M4 Memory – 256 KB RAM Storage – 512 KB flash DSP Sensors – 5 Analog frontends (AFEs) measuring: PPG (photoplethysmography) ECG (electrocardiography) Skin temperature BIA (bioelectrical impedance analysis) Galvanic skin response (GSR) I/Os – SPI, I2C PMIC Security units The sensors will enable measurements […]

F68 Sports Smartwatch Unboxing

Makibes F68 is a smartwatch with fitness features (HRM, pedometer…) and smartphone notification support, that is supposed to last around one week on a charge, and certified with an IP67 ingress protection rating. GearBest asked me if I wanted to review that model since SMA-Q watch was a disappointment, and I accepted so I have yet another smartwatch to try out. Today. I’ll take a few pictures of the watch and accessories, better writing a full review in one or two weeks. The package looks quite nice, but one detail is quite revealing: there’s no Makibes brand, nor F68 model name anywhere, and it looks exactly like FlyShark BW410 reported a few days ago by Charbax, so it must be an OEM design that will show up under multiple brand names, not only Makibes. The watch is not fully assembled, and instead the watch face comes with two watch bands, […]

Makibes F68 is a $35 IP67 Rated Sports Smartwatch with HRM & 7-Days Battery Life

So far my quest for a smartwatch as not been successful, with massive disappointments with both No.1 D3 smartwatch and SMA-Q color e-Paper smartwatch, with the latter completely failing after a week. The next potential candidate is Makibes F68 with similar features as SMA-Q, but instead with a grayscale display, IP67 ingress protection rating which should make it suitable for swimming (apparently not, see comments), as well as a promised 7-day battery life during “normal usage”. Makibes F68 specifications: MCU/Memory/Storage – Not disclosed but it’s supposed to run Nucleus RTOS. Display – 1″ round capacity touchscreen display, 128×128 resolution, always on Connectivity – Bluetooth 4.0 Sensors – 3-axis accelerometer and gyroscope Battery – 180 mAh charged via magnetic connector Dimensions – 38 x38 x 10 mm (aluminum alloy material) Weight – 31 grams IP Rating – IP67 meaning it’s been tested for 30 minutes under one meter of water. The […]

SMA-Q e-Paper Smartwatch Unboxing and Details

When I first discovered SMA-Q smartwatch, I really found it interesting with its always-on color e-Paper display, Bluetooth 4.0 connectivity, heart rate monitor, and promise of 30-day battery life (standby) for just $56. GearBest send me one sample so that I can have a close look at this interesting smartwatch and fitness tracker. I’ll start by unboxing the watch, and checkout some details that were unclear in the specifications. I received it in a retail package that calls it SMA WATCH-Q instead of SMA-Q watch with a link to the official website. On one side we’ll get the specifications, all in Chinese, but even if you can read, it’s clear the watch supports Bluetooth 4.0 and Android 4.4+ IOS7.0+ as announced in the specs, and we also learned a 150mAh battery is included, and it’s compliant with IP65 ingrees protectin ratings meaning it’s “protected from total dust ingress and low […]

Thunderboard Wear is a $75 Smartwatch Development Board by Silicon Labs

A few days ago I watched an ARMDevices.net’s video about an ARM’s smartwatch reference design running mbed OS 3.0, powered by a Silicon Labs EFM32 Giant Gecko Cortex M3 MCU, and promising up to 2 months battery life on a 160 mAh battery. While I could not find the full details about the reference design, I noticed Silicon Labs also launched a development board called Thunderboard Wear, based on the same platform, just quite bigger, and still wearable… (Sort of) Thunderboard Wear specifications: MCU – Silicon Labs EFM32GG995F1024 ARM Cortex-M3 MCU up to 48 MHz with 128 kB RAM,1 MB Flash External Memory – 256 kB external SRAM External Storage – micro SD card slot Display – 128×128 pixel Memory LCD from Sharp Connectivity – Bluetooth 4.1 smart module (Silicon Labs BGM111), upgradeable to Bluetooth 4.2 Sensors Ambient Light Sensing (ALS) and Proximity/Gesture via Silicon Labs Si1141. Optical hear-rate monitoring […]
