ESP

The ESP8266 is an impressive, low cost WiFi module suitable for adding WiFi functionality to an existing microcontroller project via a UART serial connection. The module can even be reprogrammed to act as a standalone WiFi connected device – just add power! 802.11 b/g/n protocol Wi-Fi Direct (P2P), soft-AP Integrated TCP/IP protocol stack This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller to manipulate inputs and outputs as you would normally do with an Arduino , for example, because the ESP-01 acts as a small computer. Thus, you can give a microcontroller internet access like the Wi-Fi shield does to the Arduino, or you can simply program the ESP8266 to not only have access to a Wi-Fi network, but to act as a microcontroller as well, which makes the ESP8266 very versatile.

ESP32-S2 integrates a rich set of peripherals, ranging from SPI, I²S, UART, I²C, LED PWM, TWAITM, LCD, Camera interface, ADC, DAC, touch sensor, temperature sensor, as well as up to 43 GPIOs. It also includes a full-speed USB On-The-Go (OTG) interface to enable USB communication.FeaturesMCU ESP32-S2 embedded, Xtensa® single-core 32-bit LX7 microprocessor, up to 240 MHz 128 KB ROM 320 KB SRAM 16 KB SRAM in RTC Wi­Fi 802.11 b/g/n Bit rate: 802.11n up to 150 Mbps A-MPDU and A-MSDU aggregation 0.4 µs guard interval support Center frequency range of operating channel: 2412 ~ 2484 MHz Hardware Interfaces: GPIO, SPI, LCD, UART, I²C, I²S, Camera interface, IR, pulse counter, LED PWM, TWAI (compatible with ISO 11898-1), USB OTG 1.1, ADC, DAC, touch sensor, temperature sensor 40 MHz crystal oscillator 4 MB SPI flash Operating voltage/Power supply: 3.0 ~ 3.6 V Operating temperature range: –40 ~ 85 °C Dimensions: 18 × 31 × 3.3 mm Applications Generic Low-power IoT Sensor Hub Generic Low-power IoT Data Loggers Cameras for Video Streaming Over-the-top (OTT) Devices USB Devices Speech Recognition Image Recognition Mesh Network Home Automation Smart Home Control Panel Smart Building Industrial Automation Smart Agriculture Audio Applications Health Care Applications Wi-Fi-enabled Toys Wearable Electronics Retail & Catering Applications Smart POS Machines

A low-power, open source, 2.7-inch IoT display powered by an ESP32-S2 module and featuring SHARP's Memory-in-Pixel (MiP) screen technology The Newt is a battery-powered, always-on, wall-mountable display that can go online to retrieve weather, calendars, sports scores, to-do lists, quotes…really anything on the Internet! It is powered by an ESP32-S2 microcontroller that you can program with Arduino, CircuitPython, MicroPython, or ESP-IDF. It's perfect for makers: Sharp’s Memory-in-Pixel (MiP) technology avoids the slow refresh times associated with E-Ink displays A real-time clock (RTC) was added to support timers and alarms The Newt was designed with battery operation in mind; every component on the board was chosen for its ability to operate at low power. Newt was designed to operate 'untethered,' which means it can be mounted in places where a power cord would be inconvenient, for example a wall, refrigerator, mirror, or dry-erase board. With the optional stand, desks, shelves, and nightstands are also good options. Newt is open source, and all design files and libraries are available for review, use, and modification. However, doing that is not required. Each Newt is delivered with working code with the following features: Current weather details Hourly and daily weather forecast Alarm Timer Inspirational quotes Air-quality forecast Habit calendar Pomodoro timer Oblique Strategy cards Only following the Wi-Fi provisioning instructions is needed to get started. No app downloads are required. Specifications Display Sharp Memory LCD Screen Size 2.7 inch Resolution 240 x 400 Deep Sleep Current 30 uA Refresh Rate < 0.001 s Periodic Screen Refresh Required No Input Buttons 10 capacitive pads, 1 push button RTC included Yes Speaker included Yes Power Input USB Type-C Battery included No Programming Languages Arduino, CircuitPython, ESP IDF, MicroPython Dimensions 91 x 61 x 9 mm Microcontroller Espressif ESP32-S2-WROVER Module with 4 MB flash and 2 MB PSRAM Wi-Fi capable Supports Arduino, MicroPython, CircuitPython, and ESP-IDF Deep sleep current as low as 25 μA Display 2.7-inch, 240 x 400 pixel MiP LCD Capable of delivering high-contrast, high-resolution, low-latency content with ultra-low power consumption Reflective mode leverages ambient light to eliminate the need for a backlight Time Keeping, Timers, and Alarms Micro Crystal RV-3028-C7 RTC Optimized for extreme low-power consumption (45 μA) Able to simultaneously manage a periodic timer, a countdown timer, and an alarm Hardware interrupt for timers and alarms 43 bytes of non-volatile user memory, 2 bytes of user RAM Separate UNIX time counter Buzzer Speaker/buzzer with mini class-D amplifier on DAC output A0 can play tones or lo-fi audio clips User Input Power switch Two programmable tactile buttons for Reset and Boot 10 capacitive touchpads Power Newt is designed to operate for one to two months between charges using a 500 mAH LiPo battery. The exact run time varies. (Heavy Wi-Fi use, in particular, will reduce battery charge more quickly.) USB Type-C connector for programming, power, and charging Low-quiescence voltage regulator (TOREX XC6220) that can output 1 A of current and operate as low as 8 μA. JST connector for a Lithium-Ion battery Battery-charging circuity (MCP73831) Low-battery indicator (1 μA quiescence current) Software Newt hardware is compatible with open-source Arduino libraries for ESP32-S2, Adafruit GFX (fonts), Adafruit Sharp Memory Display (display writing), and RTC RV-3028-C7 (RTC) Arduino libraries and sample programs are under development and will be available in our GitHub repository before launch CircuitPython libraries and registration are on the roadmap, with the development of a CircuitPython library for the RV-3028 real-time clock as a key dependency Included Phambili Newt – Fully assembled with pre-loaded firmware Laser-cut desktop stand Mini-magnet feet Required screws Support & Documentation Full instructions for use GitHub: Arduino Library and Codebase GitHub: Board schematics Videos of prototypes or demos (build tracked on Hackaday)
