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.
