This ESP32 LoRa SX1278 development board is described as a cost-effective and versatile networking solution. It combines a dual-core ESP32 processor (240 MHz, 600 DMIPS) with 520 KB of SRAM, 802.11 b/g/n WiFi, dual-mode Bluetooth and an SX1278 LoRa transceiver at 433 MHz with -148 dBm sensitivity, plus a 0.96 inch blue OLED display.
It also has a lithium battery charging circuit, 32 MB of flash memory and a CP2102 USB-to-serial chip, and it connects over USB Type-C.
Operating voltage is 3.3 to 7 V and the operating temperature range is -40 to +90 C. WiFi transmit power is 19.5 dBm for 802.11b, 16.5 dBm for 802.11g and 15.5 dBm for 802.11n, with data rates up to 150 Mbps at 11n HT40, 72 Mbps at HT20, 54 Mbps at 11g and 11 Mbps at 11b. The receiver sensitivity is listed as 139 dBm (as printed) and the UDP throughput as 135 Mbps.
The package includes the development board, an antenna and a connector cable. Power the module from a clean, adequately rated supply, since radio modules draw current in short bursts that a weak supply cannot follow. Keep the antenna clear of metal and ground planes, and start with the maker's example code before writing your own.
