Both types of MR001 are out of stock.
This receiver was based on a product from Lemon who have changed
the design to use a different microprocessor which does not support
the MR001 firmware.
A redesigned MR001c is in progress and availability in December is planned.
Model rail transmitters are back in stock.
Availability of the
MT01 transmit module is waiting on completion of
MyLocoSound Premium sound cards are back in stock.
Due to component shortage, MR603b is no
longer available. Its replacement, MR603c, is being worked on now and
availability is planned for August.
Limited stock of MR603 is available now.
Component shortage has again forced a redesign and MR603c, when
available, will be announced on this page.
The combination of Deltang Rx41d-v5 and
Micron MA003 is a usable substitute for Deltang's Rx60
until we can finish work on a direct replacement.
The combination is approx 10x15x8mm and can handle up to 13V and 1.5A motor
A batch of MR603
has been assembled and I will be contacting everyone
on the wait list (in the order of entry onto the list)
starting next week (1 August).
It has been found that some older Deltang transmitters will not bind
with MR603. This is almost certainly due to an issue with DSM2 implementation
in older Tx2 firmware. If you experience a problem binding, please
The first batch of MR603 sold out in 4 days.
More will be available at the end of July.
The MR603 receiver is now available for sale.
Commissioning of the Micron pick/place machine is not complete so, to
avoid further delay to MR603, a batch has been ordered from a UK PCB
assembler. They will be delivered here by 1st June and will go on sale
Mid March has arrived but still no production MR603. The status is:
Receiver development is taking longer than hoped/expected, for which
MR603 is close but not quite ready.
Pre-production boards have passed all tests which gives confidence
for production. When I started this project, the plan was to have the
receivers assembled in China.
However, the continuing global semiconductor shortage has made that infeasible;
PCB assemblers either would not quote as they had no stock of some components
or the price per board made for an unacceptable retail price.
Thus, we will be manufacturing in house. The advantage is that
components can be sourced from multiple suppliers and allows flexibility
to make sufficient stock to match demand - particularly inmportant as
more receivers are added to the range.
The downside to in-house manufacture is the startup cost and effort.
A pick/place machine has been ordered but that will take some time
to commission so initial batches of MR603 will be hand-assembled resulting
in limited availability until we are up to speed.
