NanoboyC6-JR features:

1. FCC certified ESP32-C6 mini module with the new ESP32-C6 chip.

2. HP + LP RISC-V 32-bit 160 MHz Cores.

3. 2.4 GHz Wi-Fi & IEEE 802.15.4, Bluetooth 5, Zigbee 3.0 and Thread.

4. 3.3V, 600mA LDO, 12uA deep sleep current.

5. The reversing current blocking diode D2 is rated at 1A with very low leakage current. Most 1A diodes have a much higher leakage current. 
The current for a 3.3V LDO regulator, sometimes two LDOs, has to pass through this diode. The bigger the better and lasts longer.

6. 19 GPIOs.

7. Standard WS2812B RGB. The RGB is turned off when it's not in use. It will extend battery life.

8. 5V power LED indicator and 5V presence detection.

9. User LED.

10. Larger RESET pushbutton, easy to press.

11. On board QWIIC connector with power on/off control for external sensors

12. Breadboard friendly, the battery connector is placed on the top layer.

13. Includes a set of male headers and a 2-pin JST LiPo battery connector.

14. Size: 1.25" X 0.7" or 31.75mm X 17.78mm.

15. Pin spacing: X--0.1", Y--0.6"

Unique features on the NanoboyC6-JR

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.

3. Long Reset Press (LRP) to enter bootloader mode, it's simple and easy to use, press the reset button until a red LED is lit
to enter bootloader mode. No need to press 2 buttons at the same time. Once you use it, you may like it.

In order to achieve lowest deep sleep current possible, you have 3 basic choices:

1. Use a digital switch and a resistor divider with low value. The resistor divider is only turned on for reading voltage level, can be turned off at 99.9% of time.

2. Use a resistor divider with very high value, the battery voltage level reading will be very unstable. Defeat the purpose of reading battery voltage level.

3. Do not have the resistor divider in your circuits at all. Do not monitor the battery voltage level.

The ESP32-C6 draws a higher deep sleep current (12uA) than the ESP32-PICO-V3-02.
Our NanoboyPICO-V3-02-JR board's deep sleep current is about 7-8uA. See the video at nanoboypico_v3_02_jr website.

Our more expensive DMM has an auto range feature, but unfortunately it could not display lower than 10uA, but this cheap DMM does. It's just amazing, it's even very accurate compared to other more expensive DMMs.
