La Fonera 2.0 (FON2202) Hardware Details
On October 18, Jordi Vallejo, CTO of FON, introduced the new La Fonera 2.0 (beta/developers edition) - watch it here on YouTube, and I finally received my FON 2202 yesterday. Fonera 2.0 come with a bigger footprint but also more capabilities, compared to the previous version (FON 2100). Compared to the La Fonera+ (FON 2200), the La Fonera 2.0 now comes an USB-port, which can be used to easily add a printer, scanner, external harddrive, USB-Flash-Drive,or a WebCam to the Network. E.g., I found it impressively easy to plug in USB FLash-Drive (4 GB Kingston DataTraveler) and make it accessible on the local area network (SMB) and also over the Internet (FTP).
However, let start with taking a more detailed look at the La Fonera 2.0 hardware.
However, let start with taking a more detailed look at the La Fonera 2.0 hardware.
- Flash Memory
MX 25L6405MC-20G serial flash, with a 50MHz SPI bus and 64Mbit capacity (8MByte), in 300mil SO16 format. SPI, slower than a parallel bus, potentially allows for adding additional memory devices to the bus.
The flash memory is typically used with two different filesystems. I.e.: Squashfs, a compressed read-only filesystem for Linux and JFFS2, a log-structured file system designed for use on flash devices in embedded systems. - SDRAM
Hynix hy57V561620F synchronous DRAM, 256Mbit organized in 16bit blocks, resulting in 32MByte. - Ethernet (RJ45 socket)
Ethernet controller (Marvell 88E6060) with two PHY (LFE8505). - USB 2.0 Host Controller
The NEC PD720102 open host controller interface works up to 480 Mbps. - Wireless IEEE 802.11b / 802.11g (up to 54 Mbps)
Atheros AR2315 single-chip WiFi processor running at 40 MHz.
Integrated 32-bit MIPS R4000-class processor running at 183.5 MHz - Interfacing
Serial (RS-232)
Connecting the Fonera's serial port to a PC requires an TTL to RS-232 level shifter converting +3.3V and 0V to +12V and -12V.
There is also a JTAG port on the PCB but ports pins are omitted. Fonera - JTAG connector
