Description

Breakout board for ESP8266 to Seeed Grove Headers.

Features

• hardware reset button ( for when AT+RST command fails)
• firmware update mode jumper
• Power pins broken out to jumper

Simple breakout board for the ESP8266 chip to provide wifi capability to the Teensy 3.1. Designed to take power from VIN via USB or LiPo battery and convert to 3V3 with a TLV7333 300 mA voltage regulator. Also on board is a Macronix 4 Mbit MX254006E SPI Flash memory chip. Small rgb led indicates power on, pcb antenna matched to 2.4 GHz. Can use either 26 or 40 MHz Seiko Epson crystal. The board has the same eight pins as the cheap Chinese modules as a first cut to see how hard it is to add wifi to Teensy 3.1 projects. The board is designed to solder directly on top of the Teensy just above the USB plug.

Breakout board for ATTinyX8 family of MCUs

Updated v1.1 Breadboard adapter for MxChip EMW3162 Wifi module. This is currently untested(my boards have been ordered), feedback is appreciated at spider[at]anibit[dot]com.

Quantracker Air OSD V2.1

Version 2.1 of the quantracker OSD board. Full Graphics OSD. Hardware floating point for great performance. Many peripheral functions available (I2C, SPI, SP PWM , ADC Capture Compare etc) on the breakout pins. (See the stm32f4 datasheet for more details) With STM32F4 on board The OSD is quite capable of being expanded intoto a full Flight controller with OSD. Here is a video of the maiden flight.
