RAK19004 WisBlock Green Power Module Datasheet
Overview
Description
RAK19004 is a WisBlock Power module that can harness and convert green power such as wind power, hydroelectric power, or solar power into fixed 5 V output. The module uses a TPS55165-Q1 from Texas Instruments, which is a DC-DC buck-boost converter. Upon startup, the module can have a stable 5 V output from a varying input voltage of 2 V-36 V, and its output current can also be as high as 1 A.
- The module has a minimum input voltage of 5.3 V for a startup.
- RAK19004 doesn't have a WisConnector just like the other WisBlock modules, but it is an external module with four (4) mounting holes, so you can place the module in the position that you want.
Features
- 5 V Power Output
- 2 V-36 V Power Input
- Chipset: Texas Instruments TPS55165-Q1
- Module size: 15 X 25 mm
