Hardware Description
ASM11370 uses BLE to share button events to connected target, e.g.
ASM11374 . Main system blocks:
• 3V CR2450 Cell Battery
• Microcontroller nRF52832 with ARM Cortex M4 CPU, 512kB flash and 64kB RAM
memory
• 3 Buttons which individual status, e.g. press, release, etc, are exposed via BLE
• Communication during production test is done via Universal asynchronous
receiver
transmitter interface (UART)
• Programming is done via Serial Wire Debug Interface (SWD)
• Internal DC DC converter supplies microcontroller with 1.3 V to make it more
energy efficient
• RF Tuning at 50 Ohm before and after Bluetooth Band Pass filter that feeds the
signal into a 2.4 GHz Antenna
• The Antenna type is Bended monopole
• The Antenna Gain is 0.5dBi (includes a saw filter with 2dBi)
