Description:

When you are working with microcontrollers, you often need a clear way of knowing the output of microcontroller on a particular output pin. For this purpose generally LEDs are used as indicators. This board is designed to provide eleven LEDs that can be connected to microcontrollers and used as indicators. The LEDs are the size of 0805.

Board size: 43x26mm

Description:

Have you ever soldered a smd LED on a PCB only to realize later that the polarity is wrong or the LED is simply damaged. It is quite frustrating and painful to remedy the damage. This little LED tester is designed to prevent just that. You do not have to go to a great length to figure out which end of the tiny LED is anode or cathode. You simply pick up the LED with a tweezer and place it on the two parallel strip. One end of the LED on one strip and the other end on another strip. If the LED is lit then by looking at the symbol at the bottom of the strip you know which end of it is anode or cathode. You can also find the polarity of throughol through-hole LEDs. The size of the board is: 32x40mm. This tester requires a CR2450 coin battery and it is not included. This little device can be used to test smd LEDs of variaous sizes from 201 to 1206 and larger ones.

Board size: 32x40mm

Description:

A coin cell battery holder that accepts 24 mm coin cells, on PCB with both positive and negative header pins. No soldering is required.

Description:

This little adapter is designed to provide a way to connect Atmel's ISP programmer (10 pin)  to AVR microcontrollers, for examples the microcontrollers that are placed on breadboard or PCBs and do not have an ISP10 header pin.
