There is also a possibility to add a 12mm coin cell to keep the RTC running. The Argos2D – A10x is delivered
only with a coin cell holder but without a battery.

Some JTAG debuggers, like the PEEDI JTAG, short pins #1 and #2 (VREF and VSUPPLY) of the 20-pin ARM
JTAG header (X12). On the Argos®2D A100, these pins are connected to different voltages (2V8 vs. 3V3) and
must not be shortened. If your JTAG device/connector shorts pins #1 and #2, the following switch setting
must be done on Argos®2. It disconnects 3V3 from JTAG pin #2 (VSUPPLY).
