About the Loranode esp32 V3 PCB

Loranode esp32 V3 is an open source ESP32 PCB design by Christophe45, published on GitHub. It is a 2-layer board measuring 53.3 × 101.6 mm, with 26 components from 23 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the RFM95W-868S2, MCP1700, TP4056 and HX711. By type, the board carries 7 connectors, 7 resistors, 5 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.

Loranode esp32 V3: common questions

What microcontroller does the Loranode esp32 V3 use?

The Loranode esp32 V3 is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Loranode esp32 V3 PCB?

The Loranode esp32 V3 measures 53.3 × 101.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Loranode esp32 V3?

26 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Loranode esp32 V3 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 Loranode esp32 V3 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 Loranode esp32 V3 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.
