Inside the RP2040 is a 'permanent ROM' USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar – Adafruit uses the technique on all thier native-USB boards. Just note you don't double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit, or DSP hardware support – so if you're doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you'll get close-to-M4 speeds!For peripherals, there are two I²C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO – check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).Technical Specifications

Firmware V2.4
The Elektor Laser Head transforms the Elektor Sand Clock into a clock that writes the time on glow-in-the-dark film instead of sand. In addition to displaying the time, it can also be used to create ephemeral drawings. The 5 mW laser pointer, with a wavelength of 405 nm, produces bright green drawings on the glow-in-the-dark film. For best results, use the kit in a dimly lit room. Warning: Never look directly into the laser beam!
The kit includes all the necessary components, but soldering three wires is required.
Note: This kit is also compatible with the original Arduino-based Sand Clock from 2017. For more details, see Elektor Magazine 1-2/2017 and Elektor Magazine 1-2/2018.

Using microphones with the DAC+ ADC
The DAC+ ADC is equipped with a stereo analogue input that can be configured for a wide range of input voltages. It performs best with line-level analogue sources. However, it is also possible to use it as a microphone input.
You can only use dynamic microphones. Microphones that require a power supply are not supported.
The microphone output voltage is very low. This means you need to amplify it. The DAC+ ADC has the necessary pre-amplifier already equipped. You will have to set the jumpers correctly.
The sound from the input won’t be played back automatically on the output. You will have to use some software that reads the input and outputs it again.
Setting the correct input amplifier settings for a microphone
By default, the input sensitivity is matched for line-level audio sources. This is done via a jumper on the J1 header.
Audio input to output
There is no direct connection between the input and the output. That leads to the input from the connected microphone to not be played back automatically. If you want to hear it on the output, you need to use the command line tool alsaloop can be used for this.

Raspberry Pi 5 provides two four-lane MIPI connectors, each of which can support either a camera or a display. These connectors use the same 22-way, 0.5 mm-pitch “mini” FPC format as the Compute Module Development Kit, and require adapter cables to connect to the 15-way, 1 mm-pitch “standard” format connectors on current Raspbery Pi camera and display products.These mini-to-standard adapter cables for cameras and displays (note that a camera cable should not be used with a display, and vice versa) are available in 200 mm, 300 mm and 500 mm lengths.
