RTC Battery Header
The RTC battery on the FR201 platform is used to retain BIOS CMOS settings and maintain the
real-time clock for the system. If the RTC battery is low, CMOS settings will not be retained and you
may receive an alert in the operating system. The cabled RTC battery should be replaced with a
Maxell CR2032-WK11 (or UL listed equivalent). An equivalent battery shall use a Hirose
DF13-2S-1.25c
connector to mate with the on-board connector.
Raspberry Pi Header
The Raspberry Pi header is used as the main connection between the FR202 IO board and the
motherboard. The pinout and description are provided here as a reference.
The Raspberry Pi header is designed to mimic the header on the standard Raspberry Pi 4, with
additional features. For a detailed list of standard features that this header supports, see the
Raspberry Pi documentation. The connector on the Factor 201 is female, but is pinned such that a
developer can install a male-to-male interposer and use it as a standard hat header, if the developer
notes the following changes:
1. A USB2.0 connection is added at pins 41 & 42.
2. The header’s I2C connection (typically noted as ID_SC and ID_SD) is changed to the system
I2C bus, rather than the Raspberry Pi ID bus.
3. The header’s GPIO16, 18, 20, & 21 connections are shared with the TPM (configured as SPI6
when installed). If TPM support is desired, developers must avoid implementing these pins on
the expansion header as well.
