It is a minimum set for tests during learning how to program e.g. microcontrollers LPC1111/2/3/4.
Board
The board with LPC1114 microprocessor, quartz plus capacitors for the quartz and power supply.
2 rows of headers for easy plugging in the pin into the board.
Programmer
USB-UART adapter (on FT232RL system), automatic reset and entering in bootloader mode, the programming voltage selection made with a jumper:
3.3V
5V
external voltage
The systems are easy to make at home. Main costs are LPC and FT232RL.
