The MIKROE-2535 4G LTE-NA click from MikroElektronika features the LARA-R204 multi-mode cellular module from u-blox. Even though the board is designed to use 5 V power supply the I/O voltage levels could be 3.3 V or 5 V. It communicates with the target microcontroller over UART interface, with additional functionality provided by the following pins on the mikroBUS™ line: AN, RST, CS, PWM, and INT. The board has a rich set of components to simplify development: two SMA connectors and a MicroUSB port, as well as a SIM card slot. The LARA-R204 module specifies data rates of up to 10.3 Mb/s for download, and 5.2 Mb/s for upload. The network protocol stack includes support for TCP, UDP, PPP, MMS, FTP, SMTP, SMTPS, HTTP, HTTPS, PING, and SSL. It covers LTE bands 4 and 13. This board has two RF pins with a characteristic impedance of 50 Ω. The primary antenna pin (ANT1) supports both Tx and Rx, providing the main antenna interface, while the secondary antenna pin (ANT2) supports Rx only for the LTE Rx diversity configuration.
