I bought The SAMD21 Mini is a Pro Mini-sized for the ATSAMD21G18 from bangood this is arduino zero clone platform and the form factor is really small and i think this is great replacement for arduino mini pro, this is the spec
- ATSAMD21G18 32-bit/48MHz ARM Cortex-M0+
- 256KB Flash Memory
- 32KB SRAM32KB of EEPROM (emulated in Flash)
- 22 GPIO Count
- 14 ADC Channels at 12-bit ResolutionAnalog-to-Digital and Digital-to-Analog Converters (ADC & DAC)
- RAW: 3.5V-6.0VVCC: 600mA 3.3V
- Pro Mini/Micro Layout
- Integrated USB Controller
And today i connected this modul to Bosch sensor BME 680 modul using i2c connection, for the first time this board not print any Serial println, after browsing at internet i found the serial print must be activated by adding some command below
#define Serial SerialUSB
And this the complete code if you want to try it
