Datasheet
aconno ACN52832 V1.2
The ACN52832 is a fully integrated, ultra-low power, Bluetooth Smart (former BLE) module in a small form factor which features the advanced Nordic Semiconductor nRF52832 SoC. Its capabilities are tailored for the upcoming demands of sophisticated IoT devices where small size, low power, application performance and radio-range are essential. Unlike many competitors it features a maker-friendly PCB scale package which allows a fast and easy integration without sacrificing access to its advanced peripherals and capabilities. The ACN52832 features a large number of GPIOs. Thanks to an on-board antenna its RF performance is excellent. To provide quick access to the programming interface of the SoC, the module also features a Tag-Connect connector.

3. Block Diagram
The heart of the ACN52832 module is Nordic’s highly integrated nRF52832 BLE SoC which
contains a 2.4 GHz transceiver, a 32-bit ARM® Cortex™-M4F CPU, a 512 kB flash memory, 64
kB RAMas well as analog anddigital peripherals.
It can support BLE, ANT/ANT+ and a range of proprietary 2.4 GHz protocols through so called
SoftDevices from Nordic Semiconductor, which can be downloaded freely from Nordic’s
website.
Ultra low power consumption and advanced power management enables a battery lifetime
up to several years on a coin cell battery. The 20.3 x 25 x 3 mm sized module integrates
power supply decoupling capacitors, 32 MHz and 32.768 kHz crystals, load capacitors, a DC-
DC converter, a RF matching circuit and an antenna in addition to the wireless SoC.The
module also features a small RGB LED for optical feedback.
Solely the addition of a suitable DC power source is necessary for BLE and/or ANT
connectivity. As a result of its Tag-Connect capabilities, the ease of application is further
increased. Sensor applications require additional appropriate sensors.
NFC functionality requires anexternallyconnected antenna.

4. Pin Description
The module uses a user-friendly PCB with surrounding solder pads (1.4 mm pitch) in order to
provide flexible, “through hole mounting” for rapid prototyping or, furthermore, a SMD
mounting technique for a permanent implementation.
