WISMO218 Development Kit
The WISMO218 Development Kit is used as a basis for the WISMO228 measurement via an adaptor
board and is used to perform consumption measurement using several settings. Refer to the
WISMO218 Development Kit User Guide and the WISMO218 Hardware Presentation for more
information about these settings.
Note:
The WISMO218 Development Kit can be replaced by WMP100 Development Kit once a suitable
socket-up board is available.
The WISMO218 Development Kit board is powered by the standalone power supply at VBAT; while
the WISMO228 is powered by the current measuring power supply at VBATT. It is for this reason
that the link between VBATT and VBAT (J605) must be opened (by removing the solder at the top of
the board in the SUPPLY area). Note the following information regarding both power supplies.
•
VBATT is powered by the current measuring power supply (66321B)
•
VBAT is powered by the standalone power supply (AX502) through TP602
Also take note of the following additional configuration/settings:
•
The R600 resistor and the D603 and D604 diodes (around the BAT‐TEMP connector) must
be removed.
•
The UART2 link is not used; therefore, J201, J202, J203, J204 must be opened (by removing
the solder).
•
The "FLASH‐LED" must be not used, so J602 must be opened (by removing the solder).
•
The USB link is not used; therefore, J301, J302, J303, J304, J305 must be opened (by removing
the solder).
•
Audio is not used; therefore, J702, J703, J704, J705, J605 must be opened (by removing the
solder).
•
There is no SIM detect feature on the WISMO228; therefore, J403 must be opened (by
removing the soldered).
•
Charging is not used; therefore, R602 must be removed.
•
C600 and R607 must be removed to avoid unexpected current consumption.
•
The switch, BOOT (around the "CONFIG" area), must be set to the OFF position.
