Embedded microSD (Micro Secure Digital) Card Slot
Micro820 controllers support microSD cards through an embedded microSD
card slot. It supports Class 6 and 10 SDSC and SDHC microSD cards, with
FAT32/16 formats, 32 GB maximum size. Industrial grade cards such as Swissbit
S-200u/S300u are recommended. The microSD file system supports only one file
partition. Class 4 cards are not supported.
The microSD card is primarily used for project backup and restore, as well as
datalog and recipe functions. It can also be used to configure powerup settings
(such as controller mode, IP address, and so on) through an optional
ConfigMeFirst.txt file.

Embedded RS232/RS485 Serial Port Combo
The Micro820 controller supports an embedded non-isolated RS232/RS485
combo communications port. Only one port (RS232 or RS485) can work at any
given time. The baud rate of this port supports up to 38.4 K.
The communication port uses a 6-pin 3.5 mm terminal block with pin definition
shown in the following table.
