  • Page 10: Debug

    UM3301-M 6.2 Debug By default, the debug connector is not assembly on the MB1803B-01. If necessary, the connector should be soldered. By this way, that allows to select the type of connector STDC14 or MIPI10. The foot print is compatible with the both connectors. Figure 6 CN3 assembly for debug connector It is also necessary to add some components on the bottom side of the MB1803.

    UM3301-M 6.3 Clock sources 7.2.1 HSE clock references The accuracy of the high‑speed clock (HSE) of the MCU RF board is committed to a 32 MHz crystal oscillator. The HSE oscillator is trimmed during board manufacturing. 7.2.2 LSE clock references The accuracy of the low‑speed clock (LSE) of the MCU RF board is committed to a 32.768 kHz crystal oscillator.

    Due to FCC/ISED constraints, the antenna cannot be removable. So, the board is proposed by default with a PCB antenna. This antenna is described on AN5129 available on the ST web site. Between the STM32WBA55 and the antenna, there is a passive network. This network has got two functions: makes a low pass filter and matches the impedance of the PCB antenna.

STDC14 is an extension of the MIPI10 connector. By default, on this footprint (CN3), the connector is not assembly. If some features not available on the STlinkV3EC embedded on MB1801, it’s possible to solder a MIPI10 or STDC14 connector.
