SY020-PCB Datasheet
Overview
The Kallisto® SY021-PCB is a compact sensor module which can be used for application integration as standalone module or assembled on a mezzanine using the Bottom LGA pads. The platform module is delivered with a Zephyr based firmware which makes the system functions accessible over Bluetooth LE. With the mobile Toolbox App or Python library the module can be used instantly to configure sensors and stream sensor data. A gateway solution is available with partners. Additional functionality is integrated by request and can be purchased from Sensry. Please refer to service@sensry.de for additional information.
General Features
- Stamp Module 28.5mm x 15mm
- Low power ARM Cortex-M4F microcontroller
- Bluetooth® 5.4 Low Energy
- Bluetooth® LE Antenna-on-Module
- NFC-connector-on-Module
- Wireless Qi Power Receiver
- Battery management & LiPo charger

- 4 high current low-side driver on-module
In its standard configuration, the Kallisto® sensor platform is equipped with a set of rigidly attached sensor components which facilitate the simultaneous detection of 20 different measurands at sampling rates which can be individually configured even after shipment. Optionally, additional sensor components can be connected to the SY021-PCB by making use of its multiple I/O interfaces. The integration in the firmware can be purchased from Sensry GmbH. This flexibility enables a customization according to customer requirements and application needs.

Electrical Parameters
The PCB module can be powered over USB-C, Qi Charger or LiPo-battery. The board system voltage to power the SoC and periphery is 1.8V.
Board Power & Battery Charge
Rechargeable LiPo-batteries can be purchased separately from Sensry on request.
There are different possibilities to power the board:
- USB (w/ or w/o battery)
- Stamp pads (USB_5V, VBAT)
- LiPo battery (battery soldered on stamp pads)
To recharge the battery, the board must be powered either with 5V (USB or 5V LGA pad) or via Qi Charge Coil and a standard Qi charge transmitter.
For wireless charging, a receiver coil must be assembled to the stamp pads AC1 and AC2. The recommendation is a TDK WR222230-26M8-G coil:
Any standard Qi smartphone charger can be used to charge the module. The receiver coil must be place close (< 1 mm) to the Qi charger.
LoW Side Driver
The ports are open drain low sider driver. The TI CSD13380F3 MOSFET is able drive loads up to 2.1A continuous and 13.5 A pulsed (pulse duration < 100 µs, duty cycle < 1 %). The maximum drive voltage is 12 V.
