A surprise new KIM-1 clone kit in 2021, the PAL-1. In fact, this is a Micro-KIM clone, which is a KIM-1 clone .. Look and specs are like the Micro-KIM, with some improvements like larger keys and a very affordable price ($70 in January 2021 on Tindie, my kit is on its way now from China). Motherboard, 32K RAM, second 6532 board also on Tindie now, total $60, also on its way in February 2021.
Designer and seller is a software engineer, Liu Ganning, KJXZZ, from Shenzhen, Guangdong, China

From the Tindie description:

PAL-1’s difference
First, PAL-1 is a kit, you can assemble it, test it and run it all by yourself —— an unique experience!
The PAL-1 addressing mode is completely implemented in accordance with the design of KIM-1, so it is compatible with most programs developed on KIM-1.
PAL-1 has 2K bytes ROM (complete KIM-1 Monitor), 5K bytes RAM, one 6532 RIOT chip on board, provides two 8-bit bidirectional I/Os, these I/Os are mainly used to support 23-key keyboard input and drive 6 seven-segment LED displays. In addition, PAL-1 also provides RS232 serial port to support terminal operation and 40-pin expansion port for future upgrade.The TTY/RS232 interface and expansion interface pinout uses the design of Rich Dreher and Vince Briel (MicroKIM compatible).
Besides the PAL-1 also a 6 slot motherbaord, a 32K RAM baord and a RIOT board (the second 6532 amking it a complte KIM-1) are available.

The main differences between PAL-1 and KIM-1 are illustrated by the following two figures in the “KIM-1 User Manual”.
