External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol. 294 - 295 -Each LA66 module includes a (% style="color:blue" %)**world-unique OTAA key**(%%) for LoRaWAN registration. 296 - 297 -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. 298 - 299 -LA66 is equipped with (% style="color:blue" %)**TCXO crystal**(%%) which ensures the module can achieve stable performance in extreme temperatures. 300 - 301 - 302 -== 3.2 Features == 303 - 304 -* LoRaWAN USB adapter base on LA66 LoRaWAN module 305 -* Ultra-long RF range 306 -* Support LoRaWAN v1.0.4 protocol 307 -* Support peer-to-peer protocol 308 -* TCXO crystal to ensure RF performance on low temperature 309 -* Spring RF antenna 310 -* Available in different frequency LoRaWAN frequency bands. 311 -* World-wide unique OTAA keys. 312 -* AT Command via UART-TTL interface 313 -* Firmware upgradable via UART interface 314 - 315 -== 3.3 Specification == 316 - 317 -* CPU: 32-bit 48 MHz 318 -* Flash: 256KB 319 -* RAM: 64KB 320 -* Input Power Range: 5v 321 -* Frequency Range: 150 MHz ~~ 960 MHz 322 -* Maximum Power +22 dBm constant RF output 323 -* High sensitivity: -148 dBm 324 -* Temperature: 325 -** Storage: -55 ~~ +125℃ 326 -** Operating: -40 ~~ +85℃ 327 -* Humidity: 328 -** Storage: 5 ~~ 95% (Non-Condensing) 329 -** Operating: 10 ~~ 95% (Non-Condensing) 330 -* LoRa Tx Current: <90 mA at +17 dBm, 108 mA at +22 dBm 331 -* LoRa Rx current: <9 mA 332 - 333 -== 3.4 Pin Mapping & LED == 334 - 335 - 336 - 337 -== 3.5 Example: Send & Get Messages via LoRaWAN in PC == 338 - 339 - 340 -Assume user already input the LA66 USB LoRaWAN Adapter OTAA Keys in TTN and there is already TTN network coverage. 341 - 342 - 343 -(% style="color:blue" %)**1.
