If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. This logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. This level converter also works with 2.8V and 1.8V devices. Each level converter has the capability of converting 4 pins on the high side to 4...
This is a power module for the standard bread boards (Small and Medium sized). It's concave design so will not wast your proto zone. It also supports both 5v and 3.3v (both can be enabled on each power rail).
We think it is a must to have on your workbench, really.
This is battery level display module based on battery style digital tube LED. The 5 - segment LED inside is red light and the frame is green light. There is driver chip TM1651 onboard, so the control interface is simple, just two signal lines and VCC / GND. It can be used to display the battery power.

The Wireless Charging Module can be applied in electronic equipments in common use for close wireless charging or power supply. Consisted of a transmitter and insulation coil, it could serve as a replacement for the Wireless Power Supply with stable 5V output voltage and maximum 600mA output current. Its small size and insulation coil is more suitable for...
This is a simple to use DC-DC step-up circuit. Use it to boost a lower voltage to an higher one. This circuit boasts a passive cooling system allowing you to power high power systems (led matrixes or motors for example).
In our application, especially in some outdoor applications, we often need to use the lithium battery, lithium battery charging problem is a need to solve the problem, we designed this mini lithium battery charging board.
Board size is very small , It can u solar
