STM32-OPEN32L-D - отладочный набор представляет собой плату расширения для популярной оценочной платы STM32L-DISCOVERY, позволяющий подключать к ней внешние модули расширения и создавать собственные решения на базе микроконтроллера STM32L152RBT6.
Набор оснащен множеством вспомогательных устройств, что делает его идеальным решением как для профессиональных разработчиков, так и для тех, кто только начинает осваивать  микроконтроллеры семейства STM32L.

                     
Расположение компонентов на плате:
 
                         
1) STM32L-DISCOVERY socket: for easily connecting the STM32L-DISCOVERY
2) 8I/Os + DAC interface: for connecting accessory boards such buttons, motors, etc.
3) USART2 interface: easily connects to RS232, RS485, USB TO 232, etc.
4) SPI1 / SPI2 + ADC interface
easily connects to SPI peripherals such as DataFlash (AT45DBxx), SD card, MP3 module, etc.
SPI1 features AD/DA alternative function, supports connecting AD/DA module as well
5) LCD connector: for connecting touch screen LCD
6) USART1 interface: easily connects to RS232, RS485, USB TO 232, etc.
7) PS/2 interface: for connecting PS/2 keyboard and/or mouse
8) I2C1 / I2C2 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), FRAM (FM24CLxx), etc.
9) USB interface: for connecting the STM32 development board to PC through USB connection
10) ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
11) 5V DC jack
12) 5V and VDD power input/output: usually used as power output, also common-grounding with other user board
13) MCU pins connector: all the MCU I/O ports are accessible on expansion connectors for further expansion
14) JTAG/SWD interface: for debugging/programming
15) VDD jumper
16) USB enable jumper
short the jumper to enable PC auto-detection while USB connecting
open the jumper to disable
17) Joystick jumper
short the jumper to connect the joystick to default I/Os used in example code
open the jumper to connect the joystick to custom I/Os via jumper wires
18) PS/2 interface jumper
short the jumper to connect the PS/2 interface to default I/Os used in example code
open the jumper to connect the PS/2 interface to custom I/Os via jumper wires
19) Boot mode switch: for configuring BOOT0 pin
20) AMS1117-ADJ
21) Adjustable resistor: for adjusting VDD (1.8V-3.5V, ±2%)
22) Power supply switch: 5V DC or USB
23) Power indicator
24) Joystick: five positions
