Industrial IoT
  • Qualcomm QCA4531
    This SoC features MIPS 24K @ 650 MHz CPU, 16 MB NOR Flash and 64 MB DDR2 @ 200 MHz RAM memory.
  • Low power consumption
    Carambola 3’s energy and thermal efficiency reduce development costs and avoid the need for additional thermal solutions
  • Seamless integration
    The Carambola 2 and 3 are pin-for-pin compatible, which means this updated model is great for both new projects and as an easy upgrade to existing ones
  • Cost-effective processing power and size
    Compared to Carambola 2, Carambola 3 achieves more power in an identically small form factor that’s just as easy to scale
  • Industrial-grade variant
    Carambola 3-I suits industrial applications, operating between -40°C and 85°C.
  • Optimized Network Performance
    Carambola 3's single-band SISO radio achieves data rates of up to 150 Mbps, making it an optimal choice for industrial applications.
