openPicus has launched two new development kits for the Internet of Things with either Wi-Fi or GPRS connectivity, based on their FlyportPRO modules featuring a 16-bit Microchip PIC24 MCU, and sharing the same baseboard. These kits can be used as a Web server with firmware update over the air (FOTA) (Wi-Fi version only) among other things, and support TCP, UDP, FTP, & HTTP protocols, as well as MQTT (Message Queue Telemetry Transport), a light weight messaging protocol running on top of the TCP/IP protocol, used when a small code footprint is required and/or network bandwidth is limited. openPicus FlyportPRO Wi-Fi and GPRS modules share mostly the same specifications: MCU – Microchip PIC24FJ256GB206 16-bit MCU @ 32 MHz with 256KB Flash,  96KB RAM External Storage – 16Mbit Flash memory (for FOTA), 64Kbit EEPROM Connectivity GPRS Module – SAGEM HILONC GPRS Transceiver (quad band: 850, 900, 1800, 1900 MHz) with uFL connector for external […]
