The PMOD GPS is a GPS receiver module which can add satellite positioning accuracy to any embedded system. The PmodGPS features a GlobalTop Gms-u1LP GPS antenna module that utilizes the MediaTek GPS MT3329. The PmodGPS uses a standard 6 pin connector and communicates via a two wire universal asynchronous receiver/transmitter (UART. ) The PmodGPS also has a two pin connector for control of the NRST pin to the module and the radio technical commission for maritime services or RTCM pin for differential global positioning system (DGPS) data using RTCM protocols. The PmodGPS uses UART protocol for data transmission and reception. The interface operates at a default baud rate of 9.6KBd, 8 data bits, no parity and with single stop bits. However, users can change the baud rate to predefined values that range from 4.8KBd to 115.2KBd. The PmodGPS uses sentences based on National Marine Electronics Association (NMEA) protocols for data output.
