Module description
1.Moule:4-digit LED display module 8550 triode parallel drive 2 digital tube model: 0.36 inch common positive digital tube 3 working voltage: 3.3v-5v 4 module with fixed bolt hole, easy to install 5 PCB size: 4.8cm * 2.0cm 6.Weight: 8g/PCS
Module interface description
1.VCC external 3.3v-5v voltage (can be directly connected with 5V MCU and 3.3V MCU) 2.The two-stage drive a B C D E F G H is directly connected with the IO port of the single chip microcomputer 3.The 3-bit driver D1 D2 D3 D4 is connected with the IO port of the direct MCU Note: the module can be directly connected with the IO port of MCU (12 IO ports are required) to control the display of 4-bit nixie tube without any other driver and buffer. The buyer should pay attention not to directly connect the position selection and segment selection of the module with the power supply to test the module (the module is not added with current limiting resistor, there is no problem in the connection with the IO port of the single chip microcomputer, and the direct connection with the power supply is easy to burn the digital tube)
Package Included :
2PCS x 4-digit LED display module
