Description

• A 32 bit RISC CPU running at 80MHz
• 64Kb of instruction RAM and 96Kb of data RAM
• 4MB flash memory
• Wi-Fi
• 16 GPIO pins
• I2C,SPI
• I2S
• 1 ADC

The only area the Arduino chip is better is that it has 6 ADC’s and the D1 just one, although that will very seldom a problem as you have both I2C and SPI on the chip, it is still worth taking note of this. If you need more ADC’s it is easy to add a multiplexer to incre
