This is a splittable 40 pin jumper wire, it is super flexible, can be transformed from 1-40 pin jumper wire. With some of these, you will no need to worry about the jumper wires you got before do not fit your project, just split it and go.
The LPC1114FN28 is an ARM Cortex-M0 based, mbed enabled microcontroller, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures.
It is made particularly unique by the fact that it is available in a 28-pin dual-in-line package, making it perfect for...
CD4021 is a cascadable 8bit parallel to serial shift register (basically the inverse of the 74hc595).
Sometimes you'll end up needing more digital input than the pins on your microcontroller board can readily handle. Using a parallel to serial shift register allows you collect information from 8 or more switches while only using 3 of the pins on your...
USB wireless serial data transmission module, support AT commands. With a stable CH340T do USB to serial.With this module you can do wireless serial distance transmission (100 ~ 1100m, depending on the use of the wireless module).
The very popular 595 shift register chip of the 74 series is used a lot by hobbyis because of its wide availability, good speed and simplicity. Just plug it on an arduino like shown in the tutorials and youi have 8 more outputs, put two and you have 16 more outputs ! (up to a lot of them actually, with only three pins !)
