Happy 2021!

world map2020 was a very unusual year. The COVID-19 pandemic has disrupted many people's life and unfortunately is still ravaging the world. We sincerely hope that 2021 will bring an end to the pandemic and we would like to wish all our customers, friends and suppliers a happy new year. We are very thankful for all the support we received so far and hope to continue in 2021.

NUPS - MCU UPS with NiMH Batteries

NUPS A00Many MCU applications are portable and need a mean to provide power on the go. There are many solution based on Li-ION and Li-Polymer batteries. However Lithium chemistries need sophisticated charging and protection circuits to avoid dangerous situations. For lower power projects NiMH batteries provide a simpler and safer alternative. NUPS (NiMH UPS) can provide 3.3V and 5V using 1 to 3 AA or AAA NiMH cells.

ISO01 - Compact low voltage isolated power supply

ISO01 A00While working in the lab it's often useful to have a small isolated power supply handy. Depending on the circuit configuration, ISO01 can generate galvanically isolated unipolar and symmetric voltages from a single 3.3V or 5V rail. The circuit is based on the Texas Instruments SN6501 transformer driver and uses an easy to obtain off the shelf transformer.

EFM8 Flash - Multi platform GUI Flash tool for Silicon labs EFM8UB1 USB MCUs

EFM8 Flash LinuxSilicon Labs makes many excellent 8051 based MCUs. All the MCUs in the EFM8UB line have a native USB and are pre-programmed with a USB HID bootloader. EFM8 Flash is a small GUI tool to flash the MCU from a binary file. The program uses the wxwidgets toolkit for a native look in all supported operating systems and hidapi for cross platform compatibility.

GTERM25 - DB25 Active SCSI Terminator with diagnostics LEDs

GTERMActive termination is required to get newer high performance drives working on vintage computers. Unfortunately both the Amiga and older Apple computers use a DB25 SCSI connector which makes finding a suitable terminator quite difficult. GTERM25 solves this problem providing a high performance active terminator with a DB25 connector and SCSI diagnostic LEDs.

SSR1/A - Dual AC Solid State Relay Arduino Shield

SSR1A Many MCU applications use electro-mechanical relays to control AC loads. While this is an excellent solution for occasionally turning on/off a load, it is not suited for frequent switching or PWM applications. SSR1/A is an opto-coupled solid state relay that can control two AC loads in a arduino shield form factor.

GGLABS Memory Test V0.44

GMT welcome screenGMT (GGLABS Memory Test) is a new developed memory test for vintage computers optimized for speed and coverage. The code is based on the test algorithms described in "Testing Semiconductor Memories: Theory and Practice" by A.J. van de Goor. The program is mostly in C plus small sections in assembly. It is free software and released under the GPL v3 license.

NANOBUG - Buttons and USB UART for NVIDIA Jetson Nano

NanobugThe NVIDIA Jetson Nano is a great device and its choice of I/O is ideal for user space development. If you are a kernel hacker, however, you will soon feel the need for serial console and a reset button. If you want to hack the bootloader you will also need a recovery button. The Nanobug integrates a UART to USB and buttons into a little board that plugs directly into the nano developer kit.
