Module overview

The NORA-W10 series comprises small, stand-alone, multiradio modules that integrate a powerful
microcontroller, MCU, and a radio for wireless Bluetooth and Wi-Fi communication. With the open CPU
architecture, customers can develop advanced applications running on the dual core 32-bit MCU. The
radio provides support for Wi-Fi 802.11b/g/n in the 2.4 GHz ISM band and Bluetooth Low Energy (LE)
v5.0 communications.

Supporting integrated cryptographic hardware accelerators, NORA-W10 series modules are ideal for
Internet of Things (IoT) devices, telematics, low power sensors, connected factories, connected
buildings (appliances and surveillance), point-of-sales, health devices, Artificial intelligence (AI), facial
recognition, and other design solutions that demand top-grade security.

NORA-W10 modules are compliant

with the Radio Equipment Directive (RED) and are to be certified

as modular transmitters in the: Europe (RED), Great Britain (UKCA), US (FCC), Canada (IC / ISED RSS),
Japan (MIC), Taiwan (NCC), South Korea (KCC), Australia / New Zealand (ACMA), Brazil (ANATEL),
and South Africa (ICASA). For the current approval status of certification in each country, see also

Country approvals

NORA-W10 series modules are professional grade products and support an extended temperature
range of 40 °C to +85 °C.

1.1

Module architecture

Based on the Espressif ESP32-S3 chip, NORA-W10 modules allow developers to choose either an
arbitrary external antenna with NORA-W101 or the internal antenna supported in NORA-W106 for
their application design.

These compact modules include the MCU, flash memory, crystal, and other components for
matching, filtering, antenna, decoupling, and antenna operation.

Two versions of NORA-W10 are available: NORA-W101 with antenna RF pad for the connection of an
external antenna and NORA-W106 that supports an internal PCB trace antenna.
