USB board emulates CR2032 or CR2016 coin cell battery

You can now develop CR2032 or CR2016 powered devices without having to use an actual coin cell thanks to Peter Misenko’s (Bobricius) “coin cell battery emulator CR2016/CR2032”. The USB board contains a rounded part that is compatible with CR2016 or CR2032 coin cell batteries and allows you to power your target board via USB. The board also includes holes for alligator clips to measure the current, and by extension the power consumption. Coincell battery emulator CR2016/CR2032 specifications: Power Supply 5V via Micro USB port 3V regulator 3V + GND pins for incompatible holders Power measurement – 2x alligator clip holes for Amperemeter mode (the onboard solder jumper must be open) Dimensions – Designed for a CR2016 battery (1.6 mm thick), but an adapter can be soldered for a CR2032 battery (3.2mm thick) It’s not a size fit all solution since it will only work with a specific type of battery […]

Beelink SER3 Review – A good AMD Ryzen 7 mini PC… after tweaks

Beelink has just launched a new mini PC called the SER3. It is another ‘new’ mini PC using an older CPU, in this case, an AMD mobile processor. However, the performance is surprisingly good once a few tweaks are made to the stock configuration. Beelink kindly sent one for review and I’ve looked at performance running both Windows and Ubuntu together with using an eGPU. Hardware Overview The SER3 physically consists of a 126 x 113 x 40mm (4.96 x 4.45 x 1.57 inches) square metal case. As an actively cooled mini PC, it uses AMD’s older 12 nm Zen+ Ryzen 7 3750H Picasso processor which is a quad-core 8-thread 2.3 GHz mobile processor boosting to 4.0 GHz with Radeon RX Vega 10 Graphics. The front panel has an illuminated power button, dual USB 3.0 ports, a Type-C USB 3.0 port with Alternate Mode, a 3.5mm headphone jack, and a […]
