Better low power consumption design
The ESP32 chip has a high level of low-power performance in the industry, including fine resolution clock gate control, power saving mode and dynamic voltage regulation.Designed for mobile devices, wearable electronics and Internet of things applications.Resting current 800uA ± 50uA(the instructions executed by MCU need to be read from the FLASH chip used on the board, so the power consumption cannot be reached to the limit)
The new version of WIFI LoRa 32 has redesigned the circuit part and upgraded the safety and stability of the circuit on the premise of keeping the pin order and the previous generation unchanged.Including better impedance matching and more scientific power supply circuits.Work at 30 ° C to + 80 ° C temperature range.

Perfect for the LoRaWAN protocol
The LoRa + LoRaWAN protocol is the most mature and stable narrowband Internet of things communication technology.
LoRa spread spectrum communication has the characteristics of long communication distance. Under the premise of good impedance matching and sufficient power supply, in the open area, our communication distance can reach 3Km.
On the premise of cooperating with LoRa Gateway，A gateway can communicate with more than 1,000 nodes.
LoRaWAN is the first Internet of things to propose double encryption, preventing the possibility of radio eavesdropping.
On the basis of the LoRaWAN source code provided by Semtech, we made a lot of improvements to the low-power part of the code. Within one transmission cycle of the system, only a few milliseconds were in the working state, and the rest of the time was in the deep sleep state.For example, if my application sends a set of data in 8 hours, the whole system runs in milliseconds during those 8 hours, and the rest of the time is in deep sleep.This can greatly reduce the use of batteries.

We provide routines and complete solutions for ESP32 + LoRaWAN
Through constant debugging and experimentation by our team, we successfully transplanted the LoRaWAN protocol to the ESP32 + Arduino platform, using internal RTC, and supporting deep sleep.Users only need a simple configuration to complete the application of LoRaWAN.
-
