This mature LoRaWAN stack greatly reduces the risk to make stable LoRaWAN Sensors to support different LoRaWAN servers and different countries' standards. External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol. 248 248 249 - ====(% style="color:blue" %)**DownloadandInstallApp:**(%%)====343 +Each LA66 module includes a (% style="color:blue" %)**world-unique OTAA key**(%%) for LoRaWAN registration. 250 250 345 +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. 251 251 252 - [[(%id="cke_bm_895007S"style="display:none" %)** **(%%)**DownloadLinkfor Android apk**>>https://www.dropbox.com/sh/zxwx16qb777uvkz/AABE_P8coGCQ4DAC8enH4bUya?dl=0]].(AndroidVersion Only)347 +LA66 is equipped with (% style="color:blue" %)**TCXO crystal**(%%) which ensures the module can achieve stable performance in extreme temperatures. 253 253 254 -[[image:image-20220813173738-1.png]] 255 255 350 +== 3.2 Features == 256 256 352 +* LoRaWAN USB adapter base on LA66 LoRaWAN module 353 +* Ultra-long RF range 354 +* Support LoRaWAN v1.0.4 protocol 355 +* Support peer-to-peer protocol 356 +* TCXO crystal to ensure RF performance on low temperature 357 +* Spring RF antenna 358 +* Available in different frequency LoRaWAN frequency bands. 359 +* World-wide unique OTAA keys. 360 +* AT Command via UART-TTL interface 361 +* Firmware upgradable via UART interface 362 +* Open Source Mobile App for LoRaWAN signal detect and GPS tracking. 257 257 258 -==== (% style="color:blue" %)**Use of APP:**(%%) ==== 259 259 260 260 261 - Functionandpagentroduction366 +== 3.3 Specification == 262 262 368 +* CPU: 32-bit 48 MHz 369 +* Flash: 256KB 370 +* RAM: 64KB 371 +* Input Power Range: 5v 372 +* Frequency Range: 150 MHz ~~ 960 MHz 373 +* Maximum Power +22 dBm constant RF output 374 +* High sensitivity: -148 dBm 375 +* Temperature: 376 +** Storage: -55 ~~ +125℃ 377 +** Operating: -40 ~~ +85℃ 378 +* Humidity: 379 +** Storage: 5 ~~ 95% (Non-Condensing) 380 +** Operating: 10 ~~ 95% (Non-Condensing) 381 +* LoRa Tx Current: <90 mA at +17 dBm, 108 mA at +22 dBm 382 +* LoRa Rx current: <9 mA 263 263 264 -[[image:image-20220723113448-7.png||height="995" width="450"]] 265 265 266 -**Block Explain:** 267 267 268 - 1.DisplayLA66 USB LoRaWANModule connectionstatus386 +== 3.4 Pin Mapping & LED == 269 269 270 -2.
