Is this not the cutest little display for the Raspberry Pi? It features a 2.8" display with 320x240 16-bit color pixels and a capacitive touch overlay. That's right, instead of a resistive touchscreen, which requires a fingernail or stylus, you can now use a fingerpad.
The screen looks much nicer, with a black bezel and glass overlay.
This updated design fits perfectly onto the Pi Zero, Pi 3, Pi 2 or Model A , B ! (Any Pi with a 2x20 connector) Not for use with an old Pi 1 with 2x13 connector. This version also has all 40 pins GPIO pins brought out so you can connect a 40-pin GPIO cable underneath.
The display and touchscreen uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO, CE0) as well as GPIO #25 and #24. All other GPIO are unused and you can still share the I2C pins with sensors, LED drivers, etc. Since we had a tiny bit of space, there's 4 slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.
Use it for console access or easily pop up X11 onto the PiTFT for a mini monitor, although its rather small at 320x240. Instead, we recommend using PyGame or other SDL-drawing programs to write onto the frame buffer.
Raspberry Pi computer and enclosure not included! As of July 22nd, 2015 this display comes fully assembled with tactile switches too

The ADDR pin is broken out so you can connect two of these DACs on one I2C bus, just tie the ADDR pin of one high to keep it from conflicting. Also included is a 6-pin header, for use in a breadboard. Works with both 3.3V or 5V logic.
Some nice extras with this chip: for chips that have 3.4Mbps Fast Mode I2C (Arduino's don't) you can update the Vout at ~200 KHz. There's an EEPROM so if you write the output voltage, you can 'store it' so if the device is power cycled it will restore that voltage. The output voltage is rail-to-rail and proportional to the power pin so if you run it from 3.3V, the output range is 0-3.3V. If you run it from 5V the output range is 0-5V.
Adafruit have an easy-to-use Arduino library and tutorial with a triangle-wave and sine-wave output example that can be used with any 'duino or ported to any microcontroller with I2C host. Wiring it up is easy - connect VDD to your microcontroller power pin (3-5V), GND to ground, SDA to I2C Data (on the Arduino Uno, this is A4 on the Mega it is 20 and on the Leonardo digital 2), SCL to I2C Clock(on the Arduino Uno, this is A5 on the Mega it is 21 and on the Leonardo digital 3) and listen on VOUT.

Interface
VCC: power positive
DOUT: TLL high/low level signal output
GND: power negative
AOUT: sampling current signal conversion voltage output port
Analog voltage signal output (AOUT)
Relationship between detection current and analog signal output is shown below:
Analog signal output: V0=Vcc*0.5±la*K (la is actual current through current detection pin, and K is linearity)
Eg: Input current is 1A, Vcc=5V and WS1800 linearity is 60mV/A
- When the current flows in from positive direction: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V
- When the current flows in from negative direction: V0=Vcc*0.5-la*K, V0=(2.5-0.06)V=2.44V
- If it is an AC signal: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V
The above are ideal values. There might be some precision errors.
On/Off output(DOUT)
- Make sure the current flows in from the positive direction. Adjust to the desired current warning level.
- LED will be on when current is below the setting and DOUT will be low.
- When the detected current is higher than your setting, the LED will turn off and the DOUT pin will go high.
RASPBERRY PI BOARD NOT INCLUDED
Description:
Whether you're pulling-up or pulling-down, there's no need to frown! With the PUD board from ModMyPi, adding multiple pull-up or pull-down resistors to your Raspberry Pi project is easy!
If you want to detect an "output" with your Raspberry Pi, like a button being pressed or a motion sensor detecting movement, we can configure our Raspberry Pi's GPIO pin as an "input". That input pin can be in three states (known as Tri-State logic); "high", when 3.3V is applied, "low", when the pin is connected to 0V, and "floating" when the state is undefined. Floating voltages are troublesome in electronics as the input can either read high or low depending on various fluctuations in electrical noise. Like a gate flapping open and closed in the wind, someone needs to lock the gate closed, or wedge it open. If you leave it flapping, it's likely to hit someone on their bottom on the way through!
Like our gate, the best way to avoid a floating input is to "tie" your input pin either high or low to create a default state. This is usually achieved through the use of a pull-up or pull-down resistor, either connecting our input pin via a resistor to the Pi's 3.3V to achieve a 3.3V high state, or the GND line to achieve 0V low state.
Our PUD board takes the messy wiring out of adding a pull-up or pull-down resistor to your circuit. Simply wire up the sensor output to the single pin on the PUD board and add a shunt jumper to either pull up (u) or down (d)! Therefore when you apply a signal voltage from your sensor or switch, the Pi is easily able to sense into which logic state the pin has been pulled! No more trouble from floating I/O's!
The PUD boards connects across GPIO pins 11 to 18 (17 to 24 in BCM speak), and adds a jumper configurable pull-up or pull-down resistor to each GPIO pin: 11 (BCM 17), 12 (BCM 18), 13 (BCM 27), 15 (BCM 22), 16 (BCM 23) and 18 (BCM 24). Pin 17 (3.3V) & pin 14 (GND) are used to tie the pins!
The PUD Board Features:
- Add a pull-up or pull-down resistor to your GPIO with the swap of a jumper!
- Compatible with all Raspberry Pi Models Inc. A /B /2/3 & Zero/ZeroW
- Tiny board means it's easy to integrate into any circuit - takes up just 8 GPIO pins
- Connects across GPIO pins 11 to 18 inclusive (BCM 17 to 24)
- In-line 1kΩ current limiting resistors on each GPIO
- 10kΩ pull-up or pull-down resistors on each GPIO
- All 6 GPIO pins can be configured independently
- Includes 6 x 2 Pin Shunt Jumpers & 1 x PUD Board
- Jumper configurable pull-up or pull-down resistor on pins:
- 11 (BCM 17)
- 12 (BCM 18)
- 13 (BCM 27)
- 15 (BCM 22)
- 16 (BCM 23)
- 18 (BCM 24).
- Pin 17 (3.3V) & Pin 14 (GND) are used to tie the pins!
- To pull pin up, connect the jumper across "u" and the center pin
- To pull pin down, connect the jumper across "d" and the center pin

The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted, and that the module is future proof: using Wi-Fi allows a large physical range and direct connection to the internet through a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection. The sleep current of the ESP32 chip is less than 5 µA, making it suitable for battery powered and wearable electronics applications. ESP32 supports a data rate of up to 150 Mbps, and 22 dBm output power at the antenna to ensure the widest physical range. As such the chip does offer industry-leading specifications and the best performance for electronic integration, range, power consumption, and connectivity. The operating system chosen for ESP32 is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that developers can continually upgrade their products even after their release.
