You can buy this board pre-assembled + add a Teensy 3.2 by selecting the options on the right.

Changes in this revision:

• all SMD components except for the coin-cell holder moved to top layer
• board design changed to 4-layer stack-up with 5V and GND on the inner layers to allow for more efficient routing
• pads for Teensy pins have been enlarged for easier soldering
• all GND pins now have thermal relief

Supercharged Mainboard for Teensy 3.1 and 3.2 (TEENSY NOT INCLUDED)

Breaks out ALL TEENSY PINS, including RESET and PROGRAM

Based on the Arduino DUE footprint, you can use Arduino DUE and MEGA prototype boards to expand your projects

Compatible with most Arduino UNO R3 Shields

Onboard 5v and 3.3v regulators give you plenty of power for your projects

Onboard ESP-8266 model-12E (pre-installed) adds WIFI functionality

Dedicated port for BT-12/HC-05/HC-06 Bluetooth master/slave module (module not included)

Dedicated port for NRF24L01+ 2.4ghz radio transceiver (module not included)

• BOARD CAN BE POWERED THROUGH TEENSY USB CONNECTOR (USB 3.0 port recommended)

FEATURES

• All SMD components pre-installed (excluding coin-cell holder)
• RX/TX LEDs for all 3 Teensy HW SERIAL ports - solder jumpers to disconnect LEDs from Teensy pins if desired
• LED on PIN 13 - the standard Arduino LED pin - just load the BLINK sketch and go
• POWER Status LED
• LED for Bluetooth module STATE pin - lights when SERIAL connection made over Bluetooth
• RESET button - SUPPORTS BOTH Teensy 3.1 and 3.2 RESET function (included POGO-PIN must be installed)
• RESET button for ESP-12E module
• PROGRAM/FLASH buttons for ESP-12E and HC-05/06 modules
• ALL ESP-12E PINS broken out and available on end-connector - including SPI0 if using ESP-12E Module
• 32K crystal included to support Teensy RTC (user-installed)
• CR-2032 Coin-Cell battery holder supplied for Teensy Real-Time-Clock (user-installed)
• 2 5v@800ma soft-fuses to protect 5v rail
• Program pin for Teensy and available at edge connector
• All pins and connectors labeled
• Communications ports for each radio module detailed on back of board

OPTIONS

WIFI - ESP-12E MODULE OF CHOICE PRE-INSTALLED

• ESP8266 module can be disabled, or connected to Teensy pin via jumper wire (not included) to allow control of ESP8266 power state
• ESP8266 module powered by onboard 3.3V@800ma regulator - Enough power for all your Wifi needs!
• upgrade to ESP8266 ESP-07 module with external antenna for additional $3.5* >LINK<
• upgrade to ESP8266 ESP-07 module with external antenna PLUS on-board antenna for additional $5* >LINK<
• *NOTE: ESP-07 module does not break out SPI0 so it is not available on the end-connector

NRF24L01 - module not included

• 10uf Tantalum & .1uf ceramic cap provide smooth power for 2.4Ghz radio module (pre-installed)
• add standard NRF24L01 module with on-board antenna for additional $4.5 >LINK<
• add NRF24L01+ module with external antenna for additional $7 >LINK<

Bluetooth - module not included:

• add HC-05 or AT-09 programmable Bluetooth module for additional $5 [>LINK<]
• supports your compatible HC-05/HC-06/BT-12/AT-09 Bluetooth module (verify connector pinout first!)

LIGHT SOLDERING REQUIRED

Board comes with all SMD components pre-installed and tested (except coin-cell holder)

You will need to assemble/solder:

• Solder Teensy onto board
• All male/female pin headers and connectors
• Coin-cell holder
• Barrel jack
• Molex power connector

INCLUDED IN PACKAGE

TEENSY NOT INCLUDED

Arduino-Teensy v4.2 with SMD components pre-soldered

Hardware to connect Teensy

• pogo pin
• male pin headers
• SMD pin headers for bottom PAD connections
• RTC crystal

Power connectors

• 2.1mm barrel jack
• 2.54mm 2-pin male Molex connector

Headers

• (7) female pin headers
• (1) 18x2 female header
• (2) 1x3 male pin headers for SPI

You will need to install the library you will find in my github repo in order for the test sketches to work: ITEADLIB_Arduino_WeeESP8266-master_TEENSY.zip
