5.84″ INCH E PAPER ANDROID SMARTPHONE PROMISES UP TO 10 DAY BATTERY LIFE

5.84″ INCH E-PAPER ANDROID SMARTPHONE PROMISES UP TO 10-DAY BATTERY LIFE

A number of smartphone manufacturers have, for a while, been experimenting with E-paper displays with phones like the Hisense A2 and Yota’s Yotaphone 1 and 2 implementing an e-paper based display as a secondary screen. While the use of e-paper displays brought advantages like extended battery life, and reduced pressure on the eyes in bright lights, for phones like […]

BUCK BOOST BATTERY CHARGE CONTROLLER WITH MPPT AND I2C

BUCK-BOOST BATTERY CHARGE CONTROLLER WITH MPPT AND I2C

The LT8491 from Analog Devices is a buck-boost switching regulator battery charge controller that implements a constant-current constant-voltage (CCCV) charging profile used for most battery types, including sealed lead-acid (SLA), flooded, gel and lithium-ion. Applications are expected to include solar powered battery chargers (see simplified schematic above), multiple types of lead-acid battery charging, Li-ion battery chargers, battery-equipped industrial or

ONIO.ZERO MICROCONTROLLER RUNS WITHOUT A BATTERY

ONIO.ZERO MICROCONTROLLER RUNS WITHOUT A BATTERY

It’s becoming quite obvious that traditional batteries are limiting the progress of IoT devices. They are expensive, they contain harmful chemicals and most importantly All-Batteries-Will-Die. Vemund Kval Bakken chief technology officer and co-founder at ONiO say the real problem with the battery approach to IoT comes when you actually consider the battery shelf life as well as the environmental

BATTERY LITHIUM NIMH NICD CAPACITY TESTER USING ARDUINO

BATTERY (LITHIUM, NIMH, NICD) CAPACITY TESTER USING ARDUINO

The increased interest in IoT and electric automobiles around the world is driving an increase in the use of Lithium-Ion/Lithium-Polymer/NiCd/NiMH batteries as more devices and applications are using them, due to their high energy storage capacity to size ratio. This increased interest is, however, causing an increase in the number of batteries with “fake” ampere-hours

SEEEDUINO XIAO IS AN ARDUINO MICROCONTROLLER BASED ON SAMD21 CORTEX M0

SEEEDUINO XIAO IS AN ARDUINO MICROCONTROLLER BASED ON SAMD21 CORTEX M0+

Take a look at Seeeduino XIAO. What a small size and cute looking! It is the smallest member of the Seeeduino family. Seeeduino XIAO still carries the powerful CPU-ARM® Cortex®-M0+(SAMD21G18) which is a low-power Arduino microcontroller. On the other hand, this little board has good performance in processing but needs less power. As a matter of fact, it
