BLEM301 module is based on the Dialog Semiconductor DA14531 SoC configured in buck mode. With
an integrated 128Kbytes flash, 32MHz XTAL and a on board PCB antenna, it allows faster time to market
at reduced development cost.
The module, as seen in Figure 1, comprises of:
- 128kBytes (1 Mbit) SPI FLASH
- 32MHz XTAL
- 2 decoupling capacitors
- a power inductor
- a CLC filter and matching components for the printed antenna
