Original AI Thinker GPRS A9 Quad-band GSM/GPRS (800/900/1800/1900 MHz.) Modul mit

• 32 Mbit SPI NOR Flash
• 32Mbit DDR PSRAM
• RDA 32 bit RISC Core bis zu 312 MHz
• bis zu 29 GPIO
• inkl. Antenne
• uvm.

Im Vergleich zu den AI Thinker A6 und A7 Modulen erlaubt der neue AI Thinker A9 die Nutzung von beispielsweise

• ADC
• Call
• CCID
• DNS
• File
• GPIO
• gps
• I2C
• Imei
• mqtt
• SMS
• Socket
• SPI
• SSL
• UART
• usw.

AI Thinker stellt für das A9 Entwicklerboard ein kostenloses C basierendes SDK für Windows bereit. Ähnlich wie beim ESP SDK können nun auch für das GPRS A9 Modul indviduelle Pakete kompiliert werden.

• 32 Mbit SPI NOR Flash
• 32Mbit DDR PSRAM
• RDA 32 bit RISC Core up to 312 MHz
• up to 29 GPIO
• incl. Antenna
• and much more

Compared to the AI Thinker A6 and A7 Modules the AI Thinker A9 supports

• ADC
• Call
• CCID
• DNS
• File
• GPIO
• gps
• I2C
• Imei
• mqtt
• SMS
• Socket
• SPI
