IntroductionThe STEVAL-BCNKT01V1 integrated development and prototyping platform for augmented acoustic and motion sensing for IoTapplications builds on the listening and balancing capabilities of the human ear.

With the expanded capabilities of its starter kit, BlueCoin lets you explore advanced sensor fusion and signal processingfunctions for robotics and automation applications with a 4 digital MEMS microphone array, a high-performance 9-axis inertialand environmental sensor unit and time-of-flight ranging sensors.

A high-performance STM32F446 180 MHz MCU enables real-time implementation of the very advanced sensor fusionalgorithms like adaptive beamforming and sound source localization, with ready-to-use, royalty-free building blocks.

The BlueCoin can connect via the on-board BLE link to any IoT and smart industry wireless sensor network.

To upload new firmware onto the BlueCoin an external SWD debugger (not included in the starter-kit) is needed. It isrecommended to use the ST-LINK V2.1 found on any "STM32 Nucleo-64” development board.The kit includes two expansion boards for the BlueCoin Core System:• the CoinStation for software and system architecture design support, featuring two ranging sensors with time-of-flight

technology and a low-power stereo DAC• a compact Cradle host featuring an SD card interface for on-field testing and data acquisition campaign.

UM2240Power supply

UM2240 - Rev 2 page 6/28

2. VDD is regulated by STBC03J internal LDO and is used as a power supply for the STM32F446, sensors andBlueNRG-MS

3. VBAT refers to the voltage on the Li-Po battery4. VSYS voltage source is managed by the STBC03J and can be either VIN or VBAT depending on the

operating conditions

Figure 7. STEVAL-BCNCS01V1 power supply block diagram

The on-board STBC03J battery charger IC is configured by default with a charging current of 100 mA. It ispossible to modify this current by changing the R20 resistor value.Equation 1: Icℎrg = 1VR20 ∙ 200 (1)

The default 2 kΩ value for R20 hence gives: 1V2K ∙ 200 = 100mA (2)

2.2 Power on/off procedureTo power the BlueCoin board on/off there are two different procedures (see point 1 to power on and point 2 topower off).

Step 1. When the system is fed by a Li-PO battery, push the PWR button for about a second to power theboard on.

Note: This procedure is implemented thanks to the battery charger WAKE-UP feature (STBC03J)Step 2. Push the PWR button.

In the provided software examples, the microcontroller detects the click and activates the batterycharger SHUTDOWN pin to switch the power supply off.
