XBEE Shield with RS485 for Arduino UNO (XBEE RS485 Arduino UNO)
Arduino is an open-source controller board, popular among electronic enthusiasts for making interactive projects. But for those who are not familiar with electronics, adding circuits to Arduino may be tricky. That’s why keyestudio develop this XBEE sensor shield. It can help you connect most sensor modules to Arduino pretty easily. The shield extends the digital and analog interfaces into 3PIN interface. It also comes with RS485 communication and XBEE Bluetooth module interface.
1 x XBEE Shield with RS485 for Arduino UNO
Product wiki page
You can change the communication way via the jumper cap on the shield. If all the three jumpers are connected to APC, the shield will realize the XBEE Bluetooth communication. If all jumpers are connected to 485, realize the RS485 communication function.
Onboard also comes with a reset button, a D13 indicator, and some common communication pins of 2.54mm pin pitch, such as serial port, IIC, and SPI communication pins.
Besides, it also has two 2pin terminal blocks. One is VIN GND terminal block, used to supply the external power for the UNO R3 control board, with an input voltage of DC 7-12V. The other is the Servo_PWR terminal block, used for VCC voltage input/output. If not connecting the external voltage, supply 5V for the shield; if connecting the external voltage, VCC voltage is actually the external input voltage.
- Compatible with Arduino UNO R3.
- Comes with 14 digital input/output pins.
- Comes with 6 analog IO pins
- Onboard comes with a digital port power terminal block
- Comes with an external power input terminal block and a input contact pin ( power on the control board with DC 7-12V)
- Comes with an RS485 interface.
- Comes with a reset button
- Comes with a D13 indicator
- Comes with a XBEE Bluetooth interface
- Can connect three jumper caps (APC and 485) to switch the XBEE Bluetooth communication or RS485 communication.
- Comes with I2C, serial port and SPI communication pins
- Onboard comes with a DC 3.3V output pin
- Dimensions: 58.5mm x 57.5mm x 20mm
- Weight: 26.2g

4 Channels ADS1115 ADC Module (4Ch ADS1115 ADC)
For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit 12-bit precision (from our testing, Arduino library can only give a 12-bit reading) at 860 samples/second over I2C interface/protocol. The chip can be configured as 4 single-ended input channels or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals, and is super easy to use. It is a great general-purpose 16-bit converter. Most likely you will use this module with Raspberry Pi because the Pi does not come with an ADC input pin.
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single-ended inputs. For example, your Raspberry Pi can read voltage from load cell:
