Chili2D USB Dongle Datasheet
Rev. 0.6, September 2019
GENERAL DESCRIPTION
The Chili2D module is a fully-featured Thread-certified wireless
USB dongle solution for IEEE 802.15.4 communications in the
2.4GHz band. It pairs the Cascoda CA-8211 SMARTRange™
transceiver modem with the Nuvoton M2351 Cortex
®
-M23
TrustZone
®
microcontroller.
With industry leading power consumption and sensitivity
performance, it delivers unparalleled range without external
amplifier components, thus providing whole-house connectivity
in any market on the planet.

application or coprocessor for hosts running Linux within a
Thread mesh network
● Cascoda SDK, making full use of CMake as a build system
● Code available open-source on GitHub
BENEFITS
Equipment cost: Increased range removes the need for
external power amplifiers, thereby reducing component BOM.
Installation cost: Greater datalink reliability lessens the need
for skilled installers, and the consumer can self-install.
Maintenance cost: Lower power consumption means that
batteries last longer, thereby minimising maintenance cost.
Development time: Use of pre-certified module minimises
product development time.
APPLICATIONS
● Home and building automation
● Consumer electronics
● Lighting systems
● Heating, ventilation & air-conditioning systems (HVAC)
● Smart grid (AMI/AMR)
● Asset tracking (active RFID)
● Industrial control and monitoring
● Assisted living & telecare
