New in 2020 - radio module comes with a protective tin to keep it a little safer from the elements. Packet radio with ready-to-go Arduino libraries. 900 MHz radio version, used for 868MHz or 915MHz transmissionreception. Simpler than WiFi or BLE, you dont have to associate, pair, scan, or worry about connections.

WiFi LoRa 32 is a classic IoT dev-board. The newly launched V3 version has the same pin sequence as the V2 version and retains Wi-Fi, BLE, LoRa, OLED display, and other functions. MCU ESP32-S3, LoRa Chip SX1262, USB Socket Type-C. Upgraded V3 version has better impedance matching of RF circuits. When you use esp32 oled lora, you need to use 2pcs together. One is used for receiving and another for sending. It is the best option for smart cities, farms, homes, industrial control, house security, wireless meter reading, and IoT developers. What you will get 2 X ESP32 Lora V3 development board 2 X 915MHz Antenna 2 X JST 1.25mm-2P Connector cable 2.54 pin no welding 2 X Protective Case for lora board.

HopeRF RFM95W 915Mhz - LoRaTM Ultra Long Range Wireless Transceiver functionally comparable to SX1276. The RFM95W transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity while minimizing current consumption.. Using Hope RFs patented LoRaTM modulation technique RFM95W can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials.. The high sensitivity combined with the integrated 20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness.. LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption..

ChipCH9102. FeatureAdd the SMA and TP4054 to the board,which make it can do more things. AdvantageIn terms of the power switch, we have changed the switching interaction mode,SMA antenna can enhance signal transmission. PaxcounterPaxcounter is an ESP32 MCU based device for metering passenger flows in realtime. It counts how many mobile devices are around. This gives an estimation how many people are around. Data transmissionData can either be be stored on a local SD-card, transferred to cloud using LoRa WAN network or MQTT over TCPIP, or transmitted to a local host using serial SPI interface.
