Product detailed description
The latest version of a development kit for wearable electronics in the shape and size of a watch. The kit is based on the ESP32 microcontroller clocked at 240MHz, which includes WiFi and Bluetooth. Also included on the kit board is a BMA423 3-axis accelerometer, PCF8563 real-time clock, LED, vibration motor and speaker. The power supply is provided by a 3.7V Li-ON battery, which is charged via a microUSB connector.
FreeRTOS is used as the operating system. Programming is done via the microUSB connector.

Bude to hračka na dlouhé zimní večery. Možností využití je jistě spousta. Jen odlaďování programu velmi zpomaluje příliš pomalá kompilace v Arduino IDE. Hlavně to bude chtít ještě lepší optimalizaci spotřeby.

hodinky fajn je s nimi zábava. pro skutečné použití to chce hodně pracovat s výdrží té baterie. tedy umět psát kvalitní kód

I když jsem nekoupil zde, tak musím popupravit pana Štrunce, když se kód správně napíše, tak lze dosáhnout s připojenou Wifi i 1,5 dne na tu malou baterii :-)

Hezký vzhled i HW výbava. Jediné co bych vytknul jako zásadní problém je malá kapacita baterie která se pak projevuje velmi malou výdrží na baterie. Nevydrží na jedno nabití ani jeden den, spíše se výdrž pohybuje v řádu hodin.
