 Product Description

Proteus - Internet of things ESP32 Micro-controller - Wi-Fi and Bluetooth with Prototype Board Form Factor

Perfect for testing, early deployment, college IoT projects. The IoT-Bus Proteus is based on the Espressif 240 MHz Dual-Core ESP32 micro-controller. The Proteus offers a 240 MHz, 32-bit processor with 4Mb of flash memory and integrated WiFi and Bluetooth as well as an IOT-Bus connector in a familiar prototyping layout enabling you to easily create your own IoT solution on one board.

This board is larger and designed to make it possible to add your own circuitry to make a complete IoT solution on one board.You can use the WiFi both in station (device) mode and access point mode. It includes traditional Bluetooth as well as BLE 4.0. On-board is a 3.3V regulator and a battery charging device that enables you to switch between using USB or battery power.

The battery is automatically charged in the USB is plugged in. A status light shows if it is charging or fully charged. All ESP32 pins bar the flash pins are exposed and available for your use.

The board includes a large prototyping area that includes room for traditional DIP and through-hole components as well as SMD parts such as SOIC and SOT-23. A user LED and switch is included but not connected to any pins so you can use them how you wish. Two level shifters are included so you can interface with 5V devices. The Proteus includes both 3.3V and 5V rails. Both these rails are available whether powered by the USB or the battery as the 5V is derived from the lower voltage.

An IoT-BuS socket provides two SPI and two I2C interfaces with plenty of general purpose I/O. The Espressif ESP-WROOM-32 has been selected as the micro-controller enabling very low-cost deployment of production IoT devices. 

All together the oddWires IoT-Bus can provide Wi-Fi, Bluetooth, BLE 4.0, Ethernet (September), LoRa, and CAN Bus 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. Watch this space for more!

ESP-WROOM32 Wifi Bluetooth Combo Module



The ESP-WROOM-32 Wifi Bluetooth combo module is ultra high performance and ultra low-power consumption FCC-approved (2AC7Z-ESPWROOM32) Wi-Fi and Bluetooth combo wireless platform based on ESPRESSIF ESP32 chipset. It integrates a dual-core processor, 448 KByte ROM,520 KByte SRAM,16 KByte SRAM in RTC, 802.11 b/g/n/e/I Wi-Fi, Bluetooth v4.2 BR/EDR & BLE, clocks & Times, abundant peripheral Interfaces and security mechanism.

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.
