The TTGO LoRA SX1276 OLED Board has a total of 36 pins. But you can use a single lithium-ion cell. Just look at the size difference of these two LoRa modules, this one is 433Mhz SX1278 and the TTGO LoRa32 is based on the SX1276 and is 868MHz. The 915MHz antenna needs to be in connection with the IPEX interface (if the antenna is not connected, it may damage the LoRa chip). Anyway, lets go ahead and take a look at the transmitter and receiver side programming. Question 1 is then, am I totally out of control, or is there a simple solution? document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()). Next step is to define pin connections. But when both modules are not in line of sight, the communication range drops to around 50 meters, which is quite low. Comments are attached directly to the project, making them viewable within Altium designer as well as through the browser interface. Learn how the send and getting LoRa packets using Arduino IDE. And the SX1276 LoRa transceiver module MOSI, SCLK, CS, DIO, RST, and MISO pins are connected to pins 27, 5, 18, 26, 14, and 19. Work fast with our official CLI. LoRa 1278 operates on the 433 MHz band (EU) or 470 MHz band (China). But anyway, during this test the LoRa32 is the winner.
