	Description:		Welcome, Orkhan Amiraslanov (@azerimaker) from The Things Industries! LoRa LoRaWAN Class A, B, C Devices Richard Ginus (TWTG) came on the show to discuss LoRa based products ThingsUNO ThingsNode JP Norair also worked on LoRaWAN systems, but talked about some of the limitations. The Things Stack The Things Network Orkhan is originally from Azerbijian and studied industrial automation and process control. He went to a German research center for AI for graduate work While there, his masters thesis involved large (64×64 cm display) Electroluminescent (EL) displays driven by an FPGA Similar to how Ben Krasnow’s EL displays work (but larger) SAMR34 SX1276 Xplained board Orkhan learned KiCad 2014 The radio module has a 0.5 mm pitch BGA, but he was able to get it fabbed by oshpark! The form factor Orkhan uses most often is the (adafruit) Feather pinout. Atmel software framework Atmel Studio Ported to PlatformIO ElectronicCats Putting device credentials onto device Spreading factor Orkhan said “kB” on the show, but later corrected. Here are the official number 51 usable bytes for the slowest data rates, SF10, SF11 and SF12 on 125kHz 115 bytes for SF9 on 125kHz ~222 usable bytes for faster rates, SF7 and SF8 on 125kHz (and SF7 on 250kHz) Andreas Spiess reached 149 kM with LoRa A weather balloon got 750 kM Fair use policy mandates no more than 1% transmitting time. Common uses for LoRaWAN is Industry / Smart City Reiner van der Lee made the Vinduino, who Chris met during early Supercon Device Marketplace Wienke is the CEO of The Things Industries called Orkhan to work on The Generic Node STM32WL Semtech licensed the SX1276, so the ST part is a SIP, not a SOC (chips connected by wires) Two version: single/dual core Dual Cortex M4 / M0+ Open source Power on the Generic Node 300 nA quiescent buck Designed to be low power 1.8 uA in sleep mode Used the Otii to measure sleep/transmit power CE testing output power 100 mW / 14 dBm in the EU US is 22 dBm (FCC testing) Created multiple outputs to allow different channels Generic Node Pricing: Probably will be $70 for low volume Hoping to get to $40 for future higher volume pricing Fractus antenna There will be a Virtual Conference about The Generic Node The Things Conference in Amsterdam Generic Node SDK Clock sourcing with ST TCXO was a problematic sourcing part Find Orkhan online @AzeriMaker Makertronika Blog Email: orkhanamiraslan@gmail.com Livestream available here: https://youtu.be/cvGaDz7wZag
