 ## IoT RedBoard - RP2350 Overview
 
-The IoT RedBoard - RP2350 is packed with hardware aimed at helping users get the most out of the RP2350. This includes multiple power inputs like USB-C and a 2-pin JST connector, Qwiic connector, standard R3 female headers, several status LEDs and also a couple specialized headers for the RP2350's high-speed transmit (HSTX) pins and its debug pins. The photo below highlights all the major components on this board that we'll cover in this Hardware Overview.
