KNX Secondary development module tpuart2
Type 1:Only core board
Type 2:core board+stm8s003test bottom board
Pin Description: 1 -- KNX+; 2 - GND; 3 -- KNX bus power down detection; 4 -- programming keys; 5 -- programming lamp; 6 -- Serial port command receiver; 7 -- Serial port command sending end; Logic level 3.3V. This module chip is: STM32 + TPUART2, which is as big as a RMB coin. Module processing KNX bus communication, users through the serial port high degree of freedom of data processing, do not need to in-depth understanding of the KNX protocol itself can quickly build their own equipment. You can do your own database, or you can use the generic database provided. You can download parameters, group addresses, and so on from ETS.
Note: Arrow needle can choose curved needle or straight needle, the default welding 8 feet straight needle
2.8 pin bending needles (suitable for vertical insertion to other boards)
3.8 pins Straight line needle (suitable for flat insertion to other boards)
Note: PCB can be changed. The following is the supporting function test board, the MCU is STM8S003, there are 4 key input, 5 LED output (including 1 dimming), 1 analog input (potentiometer). Test procedures are mainly: switch, dimming, curtain, scene and other functions, confirm the receipt of the test board source code.
