New Product Ideas / How to deal with VCC on Tiny Shields
« on: April 24, 2013, 03:57:22 AM »
Hello everyone,
I was studying the schematics of the TinyDuino and the programming adapter last weekend.
I want to create a temeprature shield as initial project to deal with TinyDuino.
What if a part on the Shield does not support 5V? If the USB Programming Shield is connected to TinyDuino, the uC and all other shields
are powered with +5v from USB. When the uC Board is powered by a battery VCC is VBAT ~3V.
Now what? Do I need to add DC/DC converters and level shifters on 2x2cm in order not to blow my shield, or should I design it to work with VBAT on VCC only and tell the users not to connect the shield while programming or debugging?
I'm just interested how TinyCircuits will design future shields which are providing more functionality compared to the breakout boards and the 16 LED Shield. How do you do that?
Thanks for your advice,
Michael.
