Newt is a battery-operated, always-on, wall-mounted display that can retrieve weather, calendars, sports scores, to-do lists, quotes...anything on the internet! It is powered by the ESP32-S2 microcontroller and you can program it using Arduino, CircuitPython, MicroPython or ESP-IDF. We think Newt is the next step in the evolution of low-power display panels. Sharp's Memory in Pixel (MiP) technology is ideal for manufacturers, avoiding the slow refresh times associated with E-Ink displays. To support timers and alarms, we also added a real-time clock (RTC). Finally, we designed the Newt with battery operation in mind—every component on the board was chosen for its ability to run with low power consumption.
This document describes the Telegesis ETRX2-PA ZigBee module, which is designed to be integrated into another device and provide a fast, simple and low-cost wireless mesh network interface. Unless explicitly stated, the content also applies to ETRX2HR-PA modules that use a Hirose U.FL coaxial antenna connector in place of the onboard ceramic antenna. Users cannot convert ETRX2-PA to ETRX2HR-PA or vice versa. The Telegesis ETRX2-PA module is based on the Ember ZigBee platform, which consists of the single-chip EM250 and the EmberZNet mesh stack compliant with the ZigBee PRO standard. Integrating the simple-to-use AT style command interface and advanced hardware design, a wide range of applications can be easily implemented. Configurable functionality often allows the use of the ETRX2-PA wireless mesh module without the need for an additional host microcontroller, saving even more integration time and cost. In addition to the Telegesis AT command set, the ETRX2-PA can be used with custom built firmware or the Ember EZSP based UART protocol interface... No RF experience or expertise is required to add this powerful wireless networking capability to our of products. ETRX2-PA offers fast integration opportunities and the shortest possible time for marketing your products.
ZigBee Lighting Reference Design with EMR32MG1 and PCB Antenna
Hamster Mix is a portable MIDI controller powered by Arduino that connects to MIDI via Bluetooth. It allows you to control effects and play MIDI notes in 5 octaves. Twelve keys and the ability to switch up and down through the octave make it easy to control the notes of an entire keyboard piano using our compact controller (about the size of a hamster). Hamster Mix connects to Mac, PC, Ipad and even mobile phones via Bluetooth. You can control any MIDI-enabled music program such as Ableton, Garage Band, FL Studio, Reaper, etc. Two additional buttons and two potentiometers allow you to set up your own custom effects. You can even use the buttons as a Bluetooth track launcher instead of a keyboard. You can control MIDI-enabled mobile applications such as GarageBand, FL Studio Mobile, Reason Compact, Audiokit Synth One, Moog applications, and more. Make music on the go with Hamster Mix, which fits in your pocket, meaning no wires or bulky equipment.
