PRODUCT SHOWCASE
Raspberry Pi Pico – available from element14
element14 has announced the availability of the first product built on
Raspberry Pi-designed silicon: Raspberry Pi Pico. This new product brings
high performance, low cost, and ease
of use to the microcontroller market,
in a $5 development kit.
The Raspberry Pi Pico is available
to purchase from https://au.element14.
com/3643332
At the heart of the Raspberry Pi Pico
is the RP2040, a Raspberry Pi-designed
micro. It features two 133MHz ARM
Cortex-M0+ cores; 264KB of on-chip
SRAM; 26 GPIO pins; dedicated hardware for commonly used peripherals
and a programmable I/O subsystem
for extended peripheral support; a
4-channel ADC with internal temperature sensor; and built-in USB 1.1 with
host and device support.
The RP2040 microcontroller offers
high performance for integer workloads, a large on-chip memory, and a
wide range of I/O options, making it
a flexible solution for a wide range of
microcontroller applications.
Key features include:
Memory: 264KB of on-chip SRAM;
2MB of on-board QSPI Flash.
Interfacing and mechanicals: 26
GPIO pins, of which three can be used
as analog inputs. 0.1-inch through-
hole pads with castellated edges for
SMT assembly.
Power: on-board power supply to
generate 3.3V for the RP2040 and external circuitry. Wide input voltage
range, from 1.8V to 5.5V, giving designers the flexibility to select their
preferred power source.
Developer tools: simple drag and
drop programming via micro-USB.
3-pin Serial Wire Debug (SWD) for
interactive debugging. C-based SDK,
MicroPython port, and extensive examples and documentation.

Crocus CT220 – the industry’s first TMR contactless current sensors
Mouser is now stocking the CT220
XtremeSense contactless current sensors from Crocus Technology.
The CT220 sensors are powered by
Crocus' XtremeSense tunnel magnetoresistance (TMR) 1D technology, which
enables them to detect slight changes in
AC or DC. The sensors offer a 2.7V to
5.5V supply voltage range and 1.2mA
supply current rating in a 5-lead SOT23
package. It measures the magnetic field
of the current flowing through a busbar or PCB trace and converts it to an
analog output voltage that represents
the field and current.
These sensors achieve a typical total
output error of ±0.5% while sensing
fields as low as 5mA. CT220 current
sensors feature an inherently high isolation, making them the ideal solution
for applications where product safety
compliance is a requirement.
These applications include motor
controls, solar inverters, power distribution units and power supplies,
and Internet of Things (IoT) devices.

Postponement of ElectroneX to September 2021
AEE, organisers of ElectroneX, have
been closely monitoring the COVID-19
situation and following recent outbreaks and border closures over the
Christmas period, and have made the
decision to postpone ElectroneX (Electronics Design and Assembly Expo) at
Rosehill Gardens in Sydney until 1516 September 2021 which also brings
the Expo back into the normal September timeframe.
This cautious approach will provide
sufficient time for the vaccine roll-out
to be implemented and for state governments to provide more certainty in
relation to their border closure policies
106
Silicon Chip
which is currently having a major impact on interstate business.
Due to the lead time that is required
for the promotion of the show and the
need for companies and visitors to be
able to freely travel to NSW, we believe
this is the best decision to help ensure
the overall success of the Expo.
In accordance with the terms and
conditions, all contracts and payments that have been made will be
transferred to the rescheduled dates.
If you have any questions in relation to the rescheduling please contact Noel Gray on 0407 943 817 or Vee
Johnson on 0422 399 818.
