External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol. 340 - 341 -Each LA66 module includes a (% style="color:blue" %)**world-unique OTAA key**(%%) for LoRaWAN registration. 342 - 343 -Besides the support of the LoRaWAN protocol, LA66 also supports (% style="color:blue" %)**open-source peer-to-peer LoRa Protocol**(%%) for the none-LoRaWAN application. 344 - 345 -LA66 is equipped with (% style="color:blue" %)**TCXO crystal**(%%) which ensures the module can achieve stable performance in extreme temperatures. 346 - 347 - 348 - 349 -== 3.2 Features == 350 - 351 -* LoRaWAN USB adapter base on LA66 LoRaWAN module 352 -* Ultra-long RF range 353 -* Support LoRaWAN v1.0.4 protocol 354 -* Support peer-to-peer protocol 355 -* TCXO crystal to ensure RF performance on low temperature 356 -* Spring RF antenna 357 -* Available in different frequency LoRaWAN frequency bands. 358 -* World-wide unique OTAA keys. 359 -* AT Command via UART-TTL interface 360 -* Firmware upgradable via UART interface 361 -* Open Source Mobile App for LoRaWAN signal detect and GPS tracking. 362 - 363 - 364 - 365 -== 3.3 Specification == 366 - 367 -* CPU: 32-bit 48 MHz 368 -* Flash: 256KB 369 -* RAM: 64KB 370 -* Input Power Range: 5v 371 -* Frequency Range: 150 MHz ~~ 960 MHz 372 -* Maximum Power +22 dBm constant RF output 373 -* High sensitivity: -148 dBm 374 -* Temperature: 375 -** Storage: -55 ~~ +125℃ 376 -** Operating: -40 ~~ +85℃ 377 -* Humidity: 378 -** Storage: 5 ~~ 95% (Non-Condensing) 379 -** Operating: 10 ~~ 95% (Non-Condensing) 380 -* LoRa Tx Current: <90 mA at +17 dBm, 108 mA at +22 dBm 381 -* LoRa Rx current: <9 mA 382 - 383 - 384 - 385 -== 3.4 Pin Mapping & LED == 386 - 387 - 388 - 389 -== 3.5 Example: Send & Get Messages via LoRaWAN in PC == 390 - 391 - 392 -Assume user already input the LA66 USB LoRaWAN Adapter OTAA Keys in TTN and there is already TTN network coverage. 393 - 394 - 395 -(% style="color:blue" %)**1.
