 Product Description

Io - Internet of things ESP32 Microprocessor - Wi-Fi and Bluetooth with IOT-Bus form factor

The Io offers a 240 MHz, 32-bit processor with 4Mb of flash memory and integrated WiFi and Bluetooth in very small form factor (approximately 2x1 inches). The Io accepts all of the IoT-Bus modules and can be bought in with male, female or stacking headers as can all of the IoT-Bus boards.

The oddWires IoT-Bus System is based on a low-cost, open design that includes multiple main boards including a minimalist, breadboard-friendly form factor (Io), an Arduino Uno-compatible format (Juno) with 5V bus transceivers allowing many, if not most, Arduino shields to function. There is also a version with a large prototyping area which enables a single-board IoT solution (Proteus). Rounding out the controller boards is a 320x240 touch screen with micro SD-Card (Apollo).

At the heart of the system is an IOT-BUS providing two SPI and two I2C interfaces with plenty of general purpose I/O. The Espressif ESP-WROOM-32 has been selected as the microcontroller enabling very low-cost deployment of production IoT devices. It offers 240Mhz, 32-bit processing with 4MB of flash as standard.

All together the oddWires IoT-Bus can provide Wi-Fi, Bluetooth, BLE 4.0, GSM/GPRS, Ethernet, LoRa, and Canbus connectivity so no matter what you are communicating with, oddWires has a solution for you.

Our first expansion boards are an opto-isolated relay controller and a motor controller capable of controlling four DC motors or two stepper motors. We also offer and fast 4-bit SDIO micro SD-Card module. Watch this space for more!

The ESP-WROOM-32 Wifi Bluetooth combo module provides SDK Firmware for fast on-line programming and open source toolchains based on GCC for development support. It is designed for Generic low power IoT sensor hub, loggers, video steaming for camera, Wi-Fi & Bluetooth enabled devices, Home automation and mesh network applications, aimed at makers, hardware engineers, software engineers and solution provides. ESP32 is a single chip 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC ultra low power 40 nm technology. It is designed and optimized for the best power performance, RF performance, robustness, versatility, features and reliability, for a wide variety of applications, and different power profiles.

ESP32 is the most integrated solution for Wi-Fi + Bluetooth applications in the industry with less than 10 external components. ESP32 integrates the antenna switch, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules. As such, the entire solution occupies minimal Printed Circuit Board (PCB) area. ESP32 is designed for mobile, wearable electronics, and Internet of Things (IoT) applications. It has many features of the state-of-the-art low power chips, including fine resolution clock gating, power modes, and dynamic power scaling.
