The AD5932 is a waveform generator providing a programmable frequency scan. Utilizing embedded digital processing allowing enhanced frequency
control the device generates synthesized analog or digital frequency-stepped waveforms.
This product from Analog Devices is Active. Sinusoidal/triangular/square wave outputs. Output frequency up to 25 Mhz. To program the AD5932, the user enters the start frequency, the increment step size, the number of increments to be made, and the time interval that the part outputs each frequency. The frequency scan profile is initiated, started, and executed by toggling the CTRL pin.
The AD5932 outputs each frequency in the range of interest fora defined length of time and then steps to the next frequency inthe scan range.

The MIPS SEAD -3
System engineering and development board is designed to provide a
low-cost means to support various CPU cores allowing the user to
evaluate the cores in an FPGA environment.
SEAD-3 also provides a user the ability to utilize the on board Xilinx
FPGA for their own custom programming when a MIPS® FM-3 module is added
to house the CPU core. When the FM-3 is added the user can then
additionally stack on a MIPS® FPGA 5b board that can house up to two
additional Xilinx XC5VLX330s providing extra design capacity.

Lazurite Sub-GHz - IoT
Lazurite Sub-GHz is an open platform microcomputer board with Lapis
Semiconductor's 16-bit low consumption microcontroller ML620Q504.
It includes a specific low-power (920 MHz band) technical certification
acquisition module that can realize communication of hundreds of meters
with low power consumption, so it is easy to realize IoT's sensor node.

Oki Semiconductor - A full range of digital ICs from RTCs to MPUs and network devices.
"With his enterprising spirit, Kibataro Oki (1848-1906) was far ahead of
his time in the late 1800s. In January 1881, convinced that the nation
was about to enter the age of communications, he founded Meikosha, the
origins of today's OKI."
Rechargeable AA cells are very popular for a large variety of
portable applications. The number of brands is also high, and the cell
quality can differ considerably. Cell capacity is sometimes different
from that specified, and the capacity often deteriorates dramatically
after a limited number of discharge cycles. ....
See Maxim Application Note - Simple Characterization Circuit for Rechargeable AA Cells
This characterization circuit, plus a PC and some software, accurately
measures the full discharge cycle for a rechargeable AA cell. Cell
capacity and output resistance can easily be determined from the curve
resulting from these measurements.
In Figure 1, the simple circuit is connected to the USB port of a PC. No
external power source is required because power is extracted from the
USB bus voltage. U1 (DS9490R) is a USB dongle that converts the USB
protocol to the 1-Wire® protocol, thereby allowing the PC to communicate
with the key circuit component (U2).
