Netgear WGR614 54Mbps Wireless Router
These routers will be going cheap, I picked one up for $40 after $30 rebate! They had some problems with the firmware and may or may not have fixed them, so they might not be selling so good.
# Atheros AR2312 "All in one Wireless CPU" runs at 180Mhz!
# Jtag 20 pins (all connections go to processor, not verified)
# RP-SMA antenna connector ?
# 16 Megs of RAM
# 4 Megs of Flash ?
# FCC-ID PY3WGR614v3
# Power supply reg chip (buck converter) TI 5001C out= 3.47V
# Wall Wart Supply 12V 1A center pin (+)
Since this is a special wireless chip, wireless drivers may be a problem for hacking, but this can make a great robotics CPU due to the serial port.
No hidden screws, remove 4 on bottom and it falls apart.
Power input Cap is 100uf @ 25V !
In the picture you can see what looks like a jtag port, 14 pins just about center picture, serial port (5V levels) to the right, power regulator upper left corner, same style antenna connector as the Belkin F5D7230 I listed here, very few chips on this board.
