Hey guys,
I finally decided to jum into the Maple platform. Now
for my project the µC(32bit ARM Cortex-M3 of the Maple)
should be able to work under 3v3 and 5v.
How can I extend it (µc) so that it can be worked under
3v3 and 5v? Thx for any help
extension of 32bit ARM Cortex-M3 on the Maple

MemberHi there,
I am not sure what you are trying to accomplish.- The actual STM32F103RBT6 processor used on the Maple does only take 3.3v as power supply. 5V is too much and will damage the processor, but the Maple board has already the necessary 3.3V voltage regulators on the board
- if you need to interface the board with 5V TTL components, make sure you use pins that are 5V-tolerant (see here in the last column called "5V?": http://leaflabs.com/docs/hardware/maple.html#maple-gpios )
Hope that helps,

ModeratorPlease give some more information explaining what .".. so that it can be worked under 3v3 and 5v" means.
For example, does it mean:
- can be powered by 5V
- can do an ADC conversion from voltages between 0 an 5V
- can take input voltages at 5V
- can drive external low-current loads at 5V
- can drive external high-current loads at 5V
- can interface with 5V TTL Serial
- can interface with 5V SPI
