Lora node esp32
About the Lora node esp32 PCB
Lora node esp32 is an open source ESP32 PCB design by Christophe45, published on GitHub. It is a 2-layer board measuring 48.3 × 88.9 mm, with 22 components from 20 distinct parts.
Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the RFM95W, MCP1700-3302E_TO92 and TP4056. By type, the board carries 6 connectors, 5 resistors, 4 ICs, 4 capacitors, 2 switches and 1 transistor.
It belongs with the rf & radio and sensors designs in this gallery.
From the project
ESP32 Lorawan beehive connected
This project is to make a connected hive that can control the weight, the internal and external temperature of the hive as well as the humidity. Data recovery is done with a Lora RFM95 module and reception of this data through a gateway connected to TTN. The data received on TTN is then sent to Node-red and sent back to Blynk's servers.
New version on test with a GPS module NOE6NV2 and an accelerometer MPU6050 used for alarm detection when the hive is moved.

Lora node esp32: common questions
What microcontroller does the Lora node esp32 use?
The Lora node esp32 is built around the ESP32-WROOM-32, from the ESP32 family.
How big is the Lora node esp32 PCB?
The Lora node esp32 measures 48.3 × 88.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Lora node esp32?
22 components, from 20 distinct parts. The full bill of materials is listed on this page.
Where can I download the Lora node esp32 design files?
From the Christophe45/ESP32-Lorawan repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Lora node esp32 design in my own project?
The repository has no license, so all rights stay with Christophe45. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Lora node esp32 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
