: Dimensions are approximately 31.5 x 29 x 14 mm , designed for easy integration into tight spaces or projects. hw-044 datasheet
Here are two standard connection diagrams for the HW-044.
Before we look at the board, let's look at the datasheet for the core IC.
The onboard DB9 connector hooks directly into standard PC COM ports, industrial PLC interfaces, or serial network equipment using a straight-through cable. Internally, it maps data through: HW-044-1 MAX3232 A: Yes, the MAX3232 chip is designed for 3
(half to equal the battery's capacity). You can desolder the default resistor and replace it using the guide below:
The onboard MAX3232 chip includes a voltage doubler/inverter charge pump circuit to generate the required RS232 voltage levels from a single low-voltage supply. 3.
