Overview Chili2D Thread IEEE802.15.4 Module

The Chili2D Thread IEEE802.15.4 module is a highly-integrated USB dongle module for developing Thread® / IEEE 802.15.4 low-power wireless network applications. It combines the Nuvoton M2351 Cortex®-M23 TrustZone® microcontroller with the Cascoda CA-8211 Thread® certified 2.4 GHz IEEE 802.15.4 transceiver modem.

  • OCF over Thread and Thread-certified component for every role
  • Industry-leading receive sensitivity of -105dBm
  • Programmable transmit power of -3dBm to +9dBm
  • Industry-leading link budget of 114dB
  • Integrated MAC low-power co-processor
  • Industrial temperature range: -40°C to +85°C
  • Wide supply voltage range: 2.1V to 3.6V
  • Chip antenna and all other RF components integrated on module
  • 16 MHz crystal for system clock and 32.768 kHz crystal for low-power RTC functionality
  • Module size: 27.00 x 21.05 mm

ARM® Cortex®-M23 TrustZone® MCU
