About KIISU SMOL

A brand new iteration of KIISU Development Board. Now smaller than ever (34x34mm) and modular!

KIISU SMOL Main Board

1. STM32WB55RGV / STM32WB55VGY main MCU, Arm Cortex-M4 MCU, 1024KB flash, 256KB RAM, 64 MHz
2. SubGhz radio CC1101, operating in the 300-348 MHz, 387-464 MHz, and 779-928 MHz bands, allowing you to control a wide range of equipment, such as gates, barriers, weather stations, and much more.
3. Built-in Sub-Ghz antenna and MS-156C3 connector for an external antenna. The built-in antenna automatically disconnects when an external antenna is connected; no soldering is required.
4. Bluetooth antenna and MS-156C3 connector for external use.
5. IR receiver and IR transmitter for receiving signals from remote controls and controlling TVs, air conditioners, and other home appliances.
6. ST25R3916 NFC chip for reading and emulating NFC and other 13.56 MHz smart cards of the ISO14443 and ISO15693 standards.
7. Built-in 512 MB SD-compatible memory card soldered on board.
8. 128x64 0.96" OLED display compatible with SSD1306.
9. 125-132 kHz RFID circuitry for reading, emulating, and writing EM4100 cards, pet tags, and tags of many other standards.
10. USB-C port for programming and control.
11.Efficient 5V to 3.3V LDO converters.
12. 2x12-pin connectors with 2.54mm step, with the same signals as the Flipper Zero and a partially compatible pinout. These connectors are designed for connecting a second Kiisu Smol board, for connecting to a breadboard, or for integration into your own device.
