I am looking for an experienced freelance engineer to create a Gerber file for a simple electronic product. The product should feature a PCB and a board size not exceeding 100mm x 100mm. It should also be designed with a high degree of accuracy, precision, and attention to detail. The engineer must have a thorough knowledge of the various board materials available, as well as the design techniques and practices needed to create a product that meets all requirements. I expect that the final product will have all holes perfectly aligned, traces perfectly soldered, and components securely mounted. Reliability and quality are of utmost importance to me, and I am confident that this is achievable with the right note of expertise.

We have a processor board [using a TI RM57] that needs a secondary board to interface with, the design work is related to the secondary board. We have begun the schematic design based on previous working boards, but are looking at options to out source this and other design work. We can provide a schematic which will need some finalisation and verification. The finished design should include finalised schematic, finalised pcb layout, finalised production files.

The projects requires the assembly of a PCBs in a plastic box (would already be delivered in the proper layout), a small solar panel and a battery pack onto a small wooden board (400x240x20mm).

AMP BRIDGE . Its Home Flex 50-amp smart charger is similar in operation to its public chargers so there is no learning curve. It can be hardwired into a 240-volt circuit (typically the home’s drier circuit) or an existing 240-volt outlet. The 23-foot cable allows for more installation locations in your garage and the whole charging unit has a sleek design Sometimes you don’t need smart-charging capabilities. Instead, you might need a durable outdoor charger that can withstand tough weather conditions. AMPUSHER is ideal for home EV charging, as well as electric lawn/farm equipment, which is a growing market. There’s no app to this one, just a rugged 40-amp charger. This unit can be hardwired or plugged into an existing 240-volt outlet and the power output is adjustable
