LoRa and ESP32 are everybody’s darlings, and when a combination in the form of these small boards appeared on our platforms, it seemed they are a perfect combination. Is this true? Let’s test them. - A 433 MHz Heltec - An 868-915MHz Heltec - An 868-915 TTGO - And as a reference the Hope RFM95 868 MHz These boards can be used as LoRa nodes and as TTN gateways. In this video we have a closer look at these features: - The ESP32 - The LoRa transceiver - The antennas - And the power management part Links: TTN Forum: http://bit.ly/2GFo0TN ESP32 LorRa Boards: http://s.click.aliexpress.com/e/2FyRn2n LoRa32u4: http://s.click.aliexpress.com/e/vnUFmAy Whisper Node Lora: http://bit.ly/2GCB0td dB vs VSWR: https://ww2.minicircuits.com/app/DG03-111.pdf Antennas: http://s.click.aliexpress.com/e/23vnqzb Supporting Material and Blog Page: http://www.sensorsiot.org/ Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess If you want to support the channel, please use the links below to start your shopping.
