NanoboyPICO-V3-02-JR

The high performance NanoboyPICO-V3-02-JR features a compact design with new features that make it a unique ESP32 board.  

It is pin and size compatible with TinyPICO board and can be used as its drop-in replacement with more features.

It's a good choice for IoT, robotics, wearable, home monitoring and home automation applications.

It can be programmed using Arduino IDE and other development tools.

 

1. The newest ESP32 PICO chip, PICO-V3-02.
2. 32-bit 240 MHz Dual Core, 8 MB internal flash and 2 MB internal PSRAM.
3. 2.4 GHz Wifi, 802.11b/g/n and Bluetooth BLE 4.2
4. 3.3V, 600mA LDO.
5. The reversing current blocking diode D2 (BAT20J) is rated at 1A with low leakage current. Most 1A diodes have a higher leakage current. 
The current for a 3.3V LDO regulator, sometimes two 3.3V LDOs, has to pass through this diode. The bigger the better and lasts longer.
6. 22 GPIOs including 4 JTAG pins are broken out.
7. Standard WS2812B RGB. The RGB can be turned off when it's not in use. It will extend battery life.
8. 5V power LED indicator.
9. User LED and user pushbutton switch.
10. U.FL ANT or Whip ANT offers greater receiving sensitivity for Wi-Fi communication.
11. Larger RESET pushbutton does not hurt your finger.
12. On board QWIIC connector with power on/off control for external sensors.
13. Breadboard friendly, the battery connector is placed on the top layer.
14. Includes a set of male and female headers and a 2-pin JST LiPo battery connector.
15. Size: 1.4" X 0.708" or 35.56mm X 17.99mm.
16. Pin spacing: X--0.1", Y--0.6".

1. A digital switch is added to turn off the battery level test circuit after the test is done. It will reduce deep sleep current significantly.
2. With a Low Pass Filter, the battery charge status LED does not flicker when a battery is not connected.
