Original Raspberry Pi B/B Plus Accessories RPI UART Expand Module UART Extend Board
5pcs*RPI UART Expand Module
The Serial Port module is specifically designed for Raspberry Pi. The module use Maxim MAX232 chip and DB9 port. So the user don’t need to connect Dupont Line and that avoid wrong wiring. User can use this module to debug Raspberry Pi easily.
–Maxim MAX232 on chip
–Raspberry Pi connection port
–Working voltage: 5V
–Two Drivers and Two Receivers
–Operates Up To 120 kbit/s
–Low Supply Current . . . 8 mA Typical
–Multidrop RS-232 Networks
The MAX220–MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available.
These parts are especially useful in battery-powered systems, since their low-power shutdown mode reduces power dissipation to less than 5µW. The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for applications where printed circuit board space is critical.
Test Bench — Connect the module to the Raspberry Pi — Open the corresponding port through Putty — Power up the Raspberry Pi, if the terminal print the boot information the module is OK. Technology Support: — wiki.52pi.com/index.php/RPI_UART_Extend_Board_SKU:EP-0017
