Iot-Bus Overview

Iot-Bus Overview

IoT-Bus Now in Store

Plug and play - the new range of oddWires open IoT-Bus boards use the Espressif ESP32 microprocessor (240Mhz, 32-bit, 4MB) for rapid, low-cost IoT development and deployment. The first controller boards drive relays and motors.

The flexible oddWires IoT-Bus comes with connectivity options including Wi-Fi, Bluetooth, Ethernet, CAN Bus, GSM, GPRS and LoRa

Two main-board form-factors:

  • Io - Very small and breadboard-friendly with option of male, female or both stackable headers
  • Proteus - larger prototyping board for easier customization and pinout access
  • Both of these boards can accept a specially designed JTAG board offering hardware debugging.

There is a 320x240 QVGA 2.4" TFT Touch Display offering plug and play display output with touch sensor together with a 4-line SDIO SD Card.

Three additional connectivity options:

  • Ethernet - add a PHY for 100M ethernet (expected September)
  • CAN Bus - CAN BUs module
  • LoRa - HOPE RFM95 integration

Two controller boards

  • Relay - opto-isolated relay board
  • Motor - two stepper or four DC motor controller

Choice of open environments for faster development and low cost deployment

  • ESP32 architecture is supported by GCC ESP-IDF (Espressif IoT Development Framework), based on open FreeRTOS and open lwIP (lightweight IP) stack for professional development.
  • Arduino IDE and libraries are supported to provide a higher-level interface for educational or hobbyist use.



Getting Started with IoT-Bus

To use the boards you will need either Arduino or esp-idf environments. 

To use Arduino you need to install the base Arduino IDE and then install the ESP32-Arduino extensions necessary to support the ESP32. esp-idf is a separate environment that is based on Free-RTOS.

If you intend to do more professional development and in particular use a multi-tasking environment that choosing esp-idf is a sensible choice. If you are already familiar with Arduino and/or are working in an educational or hobby environment then Arduino may be the better choice.
