Extremely cheap low-speed PC/USB oscilloscope with STM32 (STM32F042) microcontroller – variant of miniscope v2e with input amplifier (MCP6S21 PGA) added. This is minor update, but input PGA fixes problem with input leakage of STM32F042 allowing increasing input impedance at the same time. Quick specification follows miniscope v2a-d idea: very simple device streaming data in real […]
We wrote this whole page to try to make buyers of USBasp programmer clones aware of what’s possibly out there for sale and the conclusion we came to about the units we bought, after quite some investigative work IT SIMPLY DOES NOT REALLY WORK !!! We tried to read the flash content, and the blue led

Texas Instruments LM74500-Q1 Reverse Polarity Protection Controller is an automotive AEC Q100 qualified controller which operates in conjunction with an external N-channel MOSFET as a low loss reverse polarity protection solution. The wide supply input range of 3.2V to 65V allows control of many popular DC bus voltages such as 12V, 24V, and 48V automotive battery systems.

Cree’s CGHV14500 is a gallium-nitride (GaN) high-electron-mobility transistor (HEMT) designed specifically with high efficiency, high gain and wide bandwidth capabilities, which makes the CGHV14500 ideal for 1.2 – 1.4-GHz L-Band radar-amplifier applications. The transistor could be utilized for band-specific applications ranging from UHF through 1800 MHz. The package options are ceramic/metal flange and pill package. –

Power consumption is a crucial factor for the Internet of Things (IoT) applications, as it relies on a battery, which has a limited capacity and short service life, to carry out the device’s operations. IoT devices are often deployed in places that are physically difficult to reach making it difficult and expensive to replace them when
These modules come in different shapes and colours and can be purchased from the internet for 3 dollars only. They are therefore cheap enough to enable many Internet of Things applications like monitoring your home temperature and activity all year round (if you ever need to do that). And at this price, you’re actually better

Solarcell has some benefits over regular disposable batteries. It was designed to help you save some costs. Solarcell is powered by Lithium polymer (Li-Po) rechargeable batteries whose life cycle is about 10 years (1200 charge cycles). So imagine how many disposable batteries that you’d have used in those years (about 1200 disposable batteries). Li-Po batteries
This wireless project is a power transmission system, it works on the principle of magnetic induction. This Wireless Charging system works as the digital switched mode power supply with the transformer, which is separated into two parts: The transformer primary coil is on the transmitter, working as the transmitter coil, and the transformer secondary coil
