Доброго времени суток! Не могу понять, в чем различие этих двух микроконтроллеров? Есть ли разница в распиновке или в чем-то другом? С приставкой PB стоит 2.54$ Без PB 3.83$ Буду рад помощи!
Here’s a quick rundown of the new features: Two more 16-bit timer/counters. This is a big deal when you’re writing code that’s not backed up by an operating system and relies on the hardware for jitter-free timing. Two of each USART, SPI, and I2C serial instead of one of each. Good when you use I2C devices that have limited address spaces, or when you need to push the bits out really fast over SPI. Ten PWM channels instead of six. This (along with the extra 16-bit timers) is good news for anyone who uses PWM — from driving servos to making music. Onboard capacitive sensing hardware: Peripheral Touch Controller. This is entirely new to the ATmega328PB chip, and looks like it’ll be interesting for running capacitive sense buttons without additional ICs. It relies on Atmel’s QTouch software library, though, so it looks like it’s not a free-standing peripheral as much as an internal multiplexer with maybe some hardware-level filtering. We’ll have to look into this in detail when we get our hands on one of the chips. Плюс под них нужен бутлоадер с другими параметрами.
