1. Hardware introduction
I2C1 / I2C2 interface
1.1. What’s on board
[ Core in terface ]
1. STM32F429I-DISCO socket
for easily connecting the STM32F429I-DISCO
2. MCU pins connector
all the MCU I/O ports are accessible on
expansion connectors for further expansion
3. USB connector
USB to UART via PL2303 USB TO UART board
onboard MCU
4.
[ Other in terfaces ]
16. 5V D C jack
17. 5V/ 3.3 V power input/output
usually used as power output, also
common-grounding with other user board
18. JTAG/SWD interface
for debugging/programming
[ Jumper ]
2
easily connects to I2C peripherals such as I/O
expander (PCF8574), FRAM (FM24CLXX), etc.
5. I2S2 / I2S3 / I2C1 interface
for connecting I2S peripherals, such as Audio
module.
6. DCMI interface
for connecting camera module
7. SDIO interface
for connecting Micro SD module, features much
faster access speed rather than SPI
8. CAN1 interface
communicates with acc essory boards which
feature the CAN device conveniently
9. CAN2 interface
communicates with acc essory boards which
feature the CAN device conveniently
10. UART3 interface
easily connects to RS232, RS485, USB TO
232, etc
11. SPI1/SPI4 + AD/DA interface
easily connects to SPI peripherals such as
DataFlash (AT45DBxx), SD card, MP3 module,
etc MP3
SPI1 features AD/DA alternative function,
supports connecting AD/DA module as well
12. UART2 interface
easily connects to RS232, RS485, USB TO
232, etc
13. 8-bit FSMC interface
easily connects to peripherals such as
NandFlash, Ether net, etc
14. SAI1 interface
for connecting Audio peripherals, such as
UDA1380 etc
15. One-WIRE interface
easily connects to ONE-WIRE devices (TO-92
package), such as tem perature sensor
(DS18B20), elec tronic registrat ion num ber
(DS2401), etc.
16. Joystick jumper
short the jumper to connect the joystick to
default I/Os used in example code;
open the jumper to connect the joys tick to
custom I/Os via jumper w ires.
17. BOOT
mode switch
for configuring BOOT0 pin
18. USB TO UART jumper
[ Components ]
16. AMS1117-3.3
3.3V voltage regulator
17. PL2303
