ESP32 con WiFi & Bluetooth (Pycom WiPy 3.0)

A small, space conscious development board for the Pycom MicroPython enabled enterprise level system in package based on the ESP32 chipset featuring both WiFi and Bluetooth connectivity. The board features both a chip antenna and u.FL connector for longer wireless range in addition to an on board button and Tri-Color LED. A perfect IoT development board for those looking to program in MicroPython.

The 3.0 variation features the following upgrades:

• Deep sleep current draw fixed, now only 19.7µA
• Upgraded RAM from 512KB to 4MB
• Upgraded External FLASH from 4MB to 8MB
• Antenna select pin moved from GPIO16 to GPIO21 (P12)

Features

• Powerful CPU, BLE and state of the art WiFi radio
• 1KM WiFi range
• MicroPython enabled, the Linux of IoT for fast deployment
• Fits in a standard breadboard (with headers)
• Ultra-low power usage: a fraction compared to other connected micro controllers

Processing

• Espressif ESP32 chipset
• Dual processor WiFi radio system on chip
• Network processor handles the WiFi connectivity and the IPv6 stack
• Main processor is entirely free to run the user application
• An extra ULP-coprocessor that can monitor GPIOs, the ADC channels and control most of the internal peripherls during deep-sleep mode while only consuming 25uA

Interfaces

• 2 x UART, 2 x SPI, I2C, I2S, micro SD card
• Analog channels: 8_12 bit ADCs
• Timers: 4_16 bit with PWM and input capture
• DMA on all peripherals
• GPIO: Up to 24
