😴 15uA. with Xiao ESP32C6 with PPK2 while sleeping BASIC example

Glad to see the New Xiao living up to the hype :sleeping: it draws a :pinching_hand:tiny amount of juice. Man batteries will go a while now.
Here is some basic code that blinks the led and uses the RTC to wake up from sleep. attached are the power profiles collected.
GL :slight_smile: PJ :v:

Test code…

// Basic Sleep code Counts reboots saves the number in the RTC memory 
// and blinks USER LED (10)times , then Pauses and then sleeps. 
// Wakes Up after 30 seconds and repeats.
// Using board 'XIAO_ESP32C6' from platform esp32\3.0.0-rc1
// Paoched and Toasted by PJG
// --------------------------------------------------------------------
#include <Arduino.h>
#include "esp32-hal-gpio.h"
#include "esp_sleep.h"
#include "driver/rtc_io.h"

const int ledPin = 15; // Built-in LED pin on the Xiao ESP32C6
const int wakeUpPin = 2; // GPIO 2 as the wake-up pin

RTC_DATA_ATTR int bootCount = 0; // Counter to keep track of wake-ups

void setup() {
  // Increment boot count and print it
  //Serial.println("Processor OUT of RESET ");
  //Serial.println("Boot number: " + String(bootCount));
  pinMode(wakeUpPin, INPUT_PULLUP);

  // Blink LED 10 times
  for (int i = 0; i < 10; i++) {
    digitalWrite(LED_BUILTIN, LOW);
    digitalWrite(LED_BUILTIN, HIGH);
  // Configure wake-up sources
  //esp_sleep_enable_ext1_wakeup(1 << wakeUpPin, ESP_EXT1_WAKEUP_ANY_HIGH); // Wake on high level
  esp_sleep_enable_timer_wakeup(30 * 1000000); // 1 minute in microseconds , 30 seconds
 // Pause for 15 seconds

//  Serial.println("Going to sleep now");
//  Serial.flush();
  digitalWrite(LED_BUILTIN, HIGH);
  digitalWrite(LED_BUILTIN, LOW);
  // Enter deep sleep

void loop() {
  // This function will not be called as the device enters deep sleep

Average function run current is 30 Ma. with no optimisation.


Sleeping… Again No optimisation. some more could be squeezed :accordion:

This chip is definitely feels faster than the C3 albeit same clk’s you can tell by how responsive it is. Wifi connects faster too on my tests with the WPS. I like it! Why would you want a C3 I’m thinking?
here’s the setup, pic…

Hi PJ,
I am just now putting together a summary of sleep currents. I will post it as soon as it is done.
Preliminary results are 16mA (room temperature 25C).
Since SBD with high leakage current are used, the sleep current can easily double as the temperature rises. If you measure it with no wake-up, the temperature rise will be eliminated and the current will be around 16mA.

Hi there,
I should have called Vegas :moneybag: for the Odd’s you would… LOL nice stuff my Guy.
Looking forward to it. :star_struck: :+1:
