Review ESP8266 WiFi Witty Cloud Dev Board

ESP8266 WIFI Witty Cloud Development Board ESP-12F Module MINI Nodemcu

Description:
1. This cheap and small Wifi transciever is the perfect solution for
home Automation and IoT applications. It can be the replacement of your
NRF24L01, it can talk to your Wifi router directly through the UART
MCU's (Rx, Tx).
2. The ESP-12 module is one of the most complete of the ESP family as
it allows you to use biggest amount of pins of all of them. You can
program this module to work stand alone with the Arduino IDE or with LUA
as NodeMCU.
3. It has an LDR and a WS2812 led already on board for your projects.
The board comes with a CH40 micro USB module to program it.
4. The ESP8266 highly integrated chip, including antenna switch balun,
power management converter, so with minimal external circuitry. The
system is equipped with ESP8266 manifested leading features are: energy
saving VoIP quickly switch between the sleep / wake patterns, with
low-power operation adaptive radio bias, front-end signal processing
functions.
5. This version, the ESP8266-03 is one of the smallest versions of this module. It includes a buil-in ceramic antenna.
Specifications:
1. LDR Lignt Sensor on board
2. WS2812 Led on board
3. 3x tactile buttons (1x in the Witty board and 2x in theCH340 board)
4. Supports 3 modes: AP,STA,AP+STA
5. Dimensions: 24mm x 16mm
6. Micro USB connection for power and/or programming

AD7606 DATA Acquisition Module 200Ksps 16Bits review

Enojy Boian'review about this AD7606 DATA Acquisition Module 200Ksps 16Bits
Find more product deatails here; and view Boian's project here. 

1) Description
1. using high-precision 16-bit ADC chip AD7606
2. 8 analog inputs. 1M ohm impedance. [No negative supply, there is no front-end analog amplifier 
can be connected directly to the sensor output]
3. the input range of plus or minus 5V, plus or minus 10V. By IO control.
4. Resolution 16.
5. the maximum sampling frequency sampling rate of 200ksps. Supports eight sampling settings file 
(which can effectively reduce the jitter)
6. built-in benchmark
7. a single 5V power supply
8. SPI Interface, or 16-bit bus interface. Interface IO level can be 5V or 3.3V.
    We AD7606 module factory default is 8080 parallel interface.
    If SPI interface mode, you need to modify R1 R2 resistor configuration.
    Parallel Mode Jumper: R1 floating (not stickers), R2 10K resistor paste
    SPI interface mode jumper: R1 stickers 10K resistor, R2 floating (not stickers)
    AD7606 configuration is very simple, it has no internal registers. Range and over-sampling parameters 
are controlled via an external IO.
    Pulse frequency sampling rate provided by the microcontroller or DSP control.
    AD7606 must use a single 5V supply.
    Level communication interface between the AD7606 and SCM controlled by VIO pin. 
That VIO power supply must be connected to the microcontroller can be 3.3V can also be 5V.

 2) Boian Review details
The module has configuration resistors for this:

















The next step is to start connecting the module to Arduino. Since I will need 16 pins just for the data, and I still need to connect Reset, CS, RD and few others, I decided to use Arduino Mega. I have an Ethernet Shield installed on my Mega for other developments, and testing, so I decided to leave the shield in place for the experiment. Here is the result:















To start measurement, you need to set the Convst A and Convst B to low. 
The 2 signals can be set at different time:

If we look atthe module IcStation carefully we see that already included on the plate the 
two resistors, so it is not necessary to include them on our own and also includes 
capacitor 0.1 uF you need integrated between Vcc and GND to stabilize its feeding.
