New Product Ideas / USB Host shield

« on: September 20, 2015, 04:05:42 AM »

A USB Host shield based on MAX3421E that would be directly compatible with current USB2.0 Host and PTP2.0 libraries available.

TinyDuino Processors & TinyShields / TinyShield_NRF8001_BLE_Example + TinyScreen device conflict

« on: September 20, 2015, 04:00:53 AM »

Hi,

Trying to build a simple wireless sensor control, passing values/variable back and forth over BLE to iPhone, using tiny screen to display status of wireless sensor.

Working from TinyShield_NRF8001_BLE_Example adding Tinyscreen functionality to sketch seemed easiest way to implement something that also writes back (not only reads).

However, writing to screen stalls NRF8001. In first instance, app writes BLE status to screen and consequently stops NRF8001 from working/discoverable

Thanks in advance,

New Product Ideas / OPTO isolator board

« on: September 20, 2015, 03:34:27 AM »

A breakout for the ILD213T (or similar) Opto Isolator board. A version with transistors to correct logic, and a simple version that allows use of ILD213T as a basic low current relay (for basic switching). An I2C/SPI version to conserve pins? With separate microJST type connectors for each output of the HV/Noisy side to avoid otherwise having to connect through a 0.1" breakout shield.

New Product Ideas / MEMS Microphone breakout

« on: September 20, 2015, 03:28:52 AM »

Would be very useful to have a MEMS microphone breakout similar to the SPW2430 as offered by adafruit or ADMP401 version offered by Sparkfun. The MEMS package would fit perfectly within the XY & Z form factor of TinyDuino. Best possible implementation would involve getting around the Analog output of the MEMS microphones - A complete SPI/I2C solution

For compact projects, would be excellent to have a "Sensor" Board with a SPW2430/ADMP401 and the luminosity sensor current offered on one board sensor on one board.
